Durable materials have a wide range of uses. There is not only the hardest metal, but also the hardest and strongest wood, as well as the strongest man-made materials.
Where are the most durable materials used?
Heavy-duty materials are used in many areas of life. So, chemists in Ireland and America have developed a technology by which durable textile fibers are produced. The thread of this material is fifty micrometers in diameter. It is created from tens of millions of nanotubes, which are bonded together with the help of a polymer.The tensile strength of this electrically conductive fiber is three times higher than the strength of the web of the orb-weaving spider. The resulting material is used to make ultra-light body armor and sports equipment. The name of another durable material is ONNEX, created by order of the US Department of Defense. In addition to its use in the production of bulletproof vests, the new material can also be used in flight control systems, sensors, and engines.
There is a technology developed by scientists, thanks to which durable, hard, transparent and light materials are obtained by converting aerogels. On their basis, it is possible to produce lightweight body armor, armor for tanks and durable building materials.
Novosibirsk scientists have invented a plasma reactor of a new principle, thanks to which it is possible to produce nanotubulene, a heavy-duty artificial material. This material was discovered twenty years ago. It is a mass of elastic consistency. It consists of plexuses that cannot be seen with the naked eye. The thickness of the walls of these plexuses is one atom.
The fact that atoms are sort of nested into each other according to the “Russian nesting doll” principle makes nanotubulene the most durable material known. When this material is added to concrete, metal, plastic, their strength and electrical conductivity are significantly enhanced. Nanotubulene will help make cars and planes more durable. If the new material comes into wide production, then roads, houses, and equipment can become very durable. It will be very difficult to destroy them. Nanotubulene has not yet been introduced into wide production due to the very high cost. However, Novosibirsk scientists managed to significantly reduce the cost of this material. Now nanotubulene can be produced not in kilograms, but in tons.
The hardest metal
Among all known metals, chromium is the hardest, but its hardness depends largely on its purity. Its properties are corrosion resistance, heat resistance and refractoriness. Chrome is a whitish-blue metal. Its Brinell hardness is 70-90 kgf/cm2. The melting point of the hardest metal is one thousand nine hundred and seven degrees Celsius at a density of seven thousand two hundred kg / m3. This metal is found in the earth's crust in the amount of 0.02 percent, which is quite a lot. It is usually found as chromium ironstone. Chromium is mined from silicate rocks. 
This metal is used in industry, smelting chromium steel, nichrome and so on. It is used for anti-corrosion and decorative coatings. Chromium is very rich in stone meteorites falling to Earth.
The most durable tree
There is wood that surpasses cast iron in strength and can be compared with the strength of iron. We are talking about "Schmidt's Birch". It is also called the Iron Birch. Man does not know a more durable tree than this. It was opened by a Russian botanist named Schmidt, while in the Far East. 
Wood exceeds the strength of cast iron by one and a half times, the bending strength is approximately equal to the strength of iron. Due to such properties, iron birch could sometimes replace metal, because this wood is not subject to corrosion and decay. The hull of the ship, made of Iron birch, can not even be painted, the ship will not be destroyed by corrosion, the action of acids is also not afraid of it.
Schmidt's birch cannot be pierced by a bullet, you cannot cut it down with an ax. Of all the birches on our planet, it is the Iron Birch that is long-lived - it lives for four hundred years. Its place of growth is the Kedrovaya Pad Nature Reserve. This is a rare protected species, which is listed in the Red Book. If not for such a rarity, the heavy-duty wood of this tree could be used everywhere.
But the tallest trees in the world, sequoias, are not very durable material.
The strongest material in the universe
Graphene is the strongest and at the same time lightest material in our universe. This is a carbon plate, which is only one atom thick, but it is stronger than diamond, and the electrical conductivity is a hundred times higher than the silicon of computer chips. 
Soon graphene will leave scientific laboratories. All the scientists of the world talk today about its unique properties. So, a few grams of material will be enough to cover an entire football field. Graphene is very flexible, it can be folded, bent, rolled up.
Possible areas of its use are solar panels, cell phones, touch screens, super-fast computer chips.

The world around us is still fraught with many mysteries, but even phenomena and substances known to scientists for a long time do not cease to amaze and delight. We admire bright colors, enjoy tastes and use the properties of all kinds of substances that make our life more comfortable, safer and more enjoyable. In search of the most reliable and strong materials, man has made many exciting discoveries, and in front of you is a selection of just 25 such unique compounds!
25. Diamonds
If not everyone, then almost everyone knows this for sure. Diamonds are not only one of the most revered gemstones, but also one of the hardest minerals on Earth. On the Mohs scale (a scale of hardness in which an assessment is given by the reaction of a mineral to scratching), diamond is listed on the 10th line. There are 10 positions in the scale, and the 10th is the last and hardest degree. Diamonds are so hard that they can only be scratched with other diamonds.
24. Trapping webs of the spider species Caaerostris darwini

It's hard to believe, but the network of the spider Caerostris darwini (or Darwin's spider) is stronger than steel and harder than Kevlar. This web was recognized as the hardest biological material in the world, although now it has a potential competitor, but the data has not yet been confirmed. Spider fiber was tested for characteristics such as breaking strain, impact strength, tensile strength and Young's modulus (the property of a material to resist stretching, compression under elastic deformation), and in all these indicators, the web showed itself in an amazing way. In addition, the trapping web of the Darwin spider is incredibly light. For example, if we wrap our planet with Caaerostris darwini fiber, the weight of such a long thread will be only 500 grams. Such long networks do not exist, but the theoretical calculations are simply amazing!
23. Aerographite

This synthetic foam is one of the lightest fibrous materials in the world and is a network of carbon tubes only a few microns in diameter. Aerographite is 75 times lighter than polystyrene, but at the same time much stronger and more ductile. It can be compressed down to 30 times its original size without any harm to its extremely elastic structure. Thanks to this property, airgraphite foam can withstand loads up to 40,000 times its own weight.

A team of scientists from the California Institute of Technology and Berkeley Lab (California Institute of Technology, Berkeley Lab) has developed a new type of metallic glass that combines a near-perfect combination of strength and ductility. The reason for the uniqueness of the new material lies in the fact that its chemical structure successfully masks the brittleness of existing glassy materials while maintaining a high endurance threshold, which ultimately significantly increases the fatigue strength of this synthetic structure.
21. Tungsten carbide

Silicon carbide is one of the main materials used to make battle tanks. This compound is known for its low cost, outstanding refractoriness and high hardness, and is therefore often used in the manufacture of equipment or gear that must deflect bullets, cut or grind other hard materials. Silicon carbide makes excellent abrasives, semiconductors, and even inlays in jewelry that mimic diamonds.
19. Cubic boron nitride

Cubic boron nitride is a superhard material, similar in hardness to diamond, but also has a number of distinctive advantages - high temperature stability and chemical resistance. Cubic boron nitride does not dissolve in iron and nickel even under the influence of high temperatures, while diamond under the same conditions enters into chemical reactions rather quickly. In fact, this is beneficial for its use in industrial grinding tools.
18. Ultra High Molecular Weight Polyethylene (UHMWPE), Dyneema fiber brand

High modulus polyethylene has extremely high wear resistance, low coefficient of friction and high fracture toughness (low temperature reliability). Today it is considered the strongest fibrous substance in the world. The most amazing thing about this polyethylene is that it is lighter than water and can stop bullets at the same time! Cables and ropes made of Dyneema fibers do not sink in water, do not need lubrication and do not change their properties when wet, which is very important for shipbuilding.
17. Titanium alloys

Developed in 2003 at the California Institute of Technology, this material is renowned for its strength and durability. The name of the compound is associated with something brittle and liquid, but at room temperature it is actually unusually hard, wear-resistant, not afraid of corrosion and transforms when heated, like thermoplastics. The main areas of application so far are the manufacture of watches, golf clubs and covers for mobile phones (Vertu, iPhone).
15. Nanocellulose

Nanocellulose is isolated from wood fibers and is a new type of wood material that is even stronger than steel! In addition, nanocellulose is also cheaper. The innovation has great potential and could seriously compete with glass and carbon fiber in the future. The developers believe that this material will soon be in great demand in the production of army armor, super-flexible screens, filters, flexible batteries, absorbent aerogels and biofuels.
14. Teeth of snails of the "sea saucer" type

Earlier, we already told you about the trapping web of Darwin's spider, which was once recognized as the most durable biological material on the planet. However, a recent study showed that the limpet is the most durable biological substance known to science. Yes, these teeth are stronger than the web of Caaerostris darwini. And this is not surprising, because tiny sea creatures feed on algae growing on the surface of harsh rocks, and these animals have to work hard to separate food from the rock. Scientists believe that in the future we will be able to use the example of the fibrous structure of the teeth of limpets in the engineering industry and begin to build cars, boats and even aircraft of increased strength, inspired by the example of simple snails.
13. Maraging steel

Osmium is an incredibly dense element, and due to its hardness and high melting point, it is difficult to machine. That is why osmium is used where durability and strength are most valued. Osmium alloys are found in electrical contacts, rocketry, military projectiles, surgical implants, and many other applications.
11. Kevlar

Graphene is an allotropic modification of carbon, and its crystal lattice, just one atom thick, is so strong that it is 200 times harder than steel. Graphene looks like cling film, but breaking it is an almost impossible task. To punch through a graphene sheet, you have to stick a pencil into it, on which you will have to balance a load with the weight of an entire school bus. Good luck!
8. Carbon nanotube paper

Thanks to nanotechnology, scientists have managed to make paper that is 50,000 times thinner than a human hair. Sheets of carbon nanotubes are 10 times lighter than steel, but the most amazing thing is that they are as much as 500 times stronger! Macroscopic nanotube plates are the most promising for the manufacture of supercapacitor electrodes.
7. Metal microgrid

Here is the lightest metal in the world! The metal microgrid is a synthetic porous material that is 100 times lighter than foam. But don't let its appearance fool you, these microgrids are also incredibly strong, making them great potential for use in all sorts of engineering applications. They can be used to make excellent shock absorbers and thermal insulators, and the amazing ability of this metal to shrink and return to its original state allows it to be used to store energy. Metal microgrids are also actively used in the production of various parts for the aircraft of the American company Boeing.

Also known as graphene airgel, this material is extremely light and strong at the same time. The new type of gel has completely replaced the liquid phase with a gaseous one, and it is characterized by sensational hardness, heat resistance, low density and low thermal conductivity. Incredibly, graphene airgel is 7 times lighter than air! The unique compound is able to regain its original shape even after 90% compression and can absorb up to 900 times the weight of oil used to absorb airbrush. Perhaps in the future this class of materials will help in the fight against environmental disasters such as oil spills.

This newly discovered natural substance is formed during volcanic eruptions and is 18% harder than diamonds. However, it surpasses diamonds in a number of other parameters. Wurtzite boron nitride is one of only 2 natural substances found on Earth that is harder than diamond. The problem is that there are very few such nitrides in nature, and therefore they are not easy to study or apply in practice.
1. Lonsdaleite

Also known as hexagonal diamond, lonsdaleite is made up of carbon atoms, but in this modification, the atoms are arranged slightly differently. Like wurtzite boron nitride, lonsdaleite is a natural substance that is harder than diamond. Moreover, this amazing mineral is harder than diamond by as much as 58%! Like wurtzite boron nitride, this compound is extremely rare. Sometimes lonsdaleite is formed during a collision with the Earth of meteorites, which include graphite.
What kind of material is used in the production of plastic containers. How are plastics different from each other? Plastic
It is quite easy to determine the type of plastic if there is a marking - but what if there is no marking, but it is necessary to find out what the thing is made of ?! For quick and high-quality recognition of various types of plastics, a little desire and practical experience are enough. The technique is quite simple: the physical and mechanical properties of plastics are analyzed (hardness, smoothness, elasticity, etc.) and their behavior in the flame of a match (lighter). It may seem strange, but different types of plastics burn differently! For example, some flare up brightly and burn intensely (almost without soot), while others, on the contrary, smoke heavily. Plastic even makes different sounds when it burns! Therefore, it is so important to accurately identify the type of plastic, its brand by a set of indirect signs.
How to identify LDPE (high pressure, low density polyethylene). Burns with a bluish, luminous flame with melting and burning streaks of polymer. When burning, it becomes transparent, this property persists for a long time after the flame is extinguished. Burns without soot. Burning drops, when falling from a sufficient height (about one and a half meters), make a characteristic sound. When cooling, the polymer drops look like frozen paraffin, very soft, when rubbed between the fingers, they are greasy to the touch. Extinct polyethylene smoke has the smell of paraffin. Density of LDPE: 0.91-0.92 g/cm. cube
How to identify HDPE (low pressure, high density polyethylene). More rigid and dense than LDPE, fragile. Combustion test - similar to LDPE. Density: 0.94-0.95 g/cm. cube
How to identify Polypropylene. When introduced into a flame, polypropylene burns with a brightly glowing flame. Burning is similar to burning LDPE, but the smell is more pungent and sweetish. During combustion, streaks of the polymer are formed. When molten, it is transparent; when cooled, it becomes cloudy. If you touch the melt with a match, you can pull out a long, fairly strong thread. Drops of the cooled melt are harder than those of LDPE, they crush with a crunch with a solid object. Smoke with a sharp smell of burnt rubber, sealing wax.
How to identify Polyethylene teraphthalate (PET). Durable, tough and lightweight material. The density of PET is 1.36 g/cm3. It has good thermal stability (resistance to thermal degradation) in the temperature range from - 40° to + 200°. PET is resistant to dilute acids, oils, alcohols, mineral salts and most organic compounds, with the exception of strong alkalis and some solvents. When burning, a very smoky flame. When removed from the flame, it self-extinguishes.
Polystyrene. When bending a strip of polystyrene, it bends easily, then breaks sharply with a characteristic crack. A fine-grained structure is observed at the break. It burns with a bright, strongly smoky flame (flakes of soot soar up in thin cobwebs!). The smell is sweetish, floral. Polystyrene dissolves well in organic solvents (styrene, acetone, benzene).
How to identify polyvinyl chloride (PVC). Elastic. Slowly combustible (when removed from the flame, self-extinguishes). When burning, it smokes strongly, a bright bluish-green glow can be observed at the base of the flame. Very strong, pungent odor of smoke. During combustion, a black, carbon-like substance is formed (it is easily rubbed between the fingers into soot). Let's dissolve in carbon tetrachloride, dichloroethane. Density: 1.38-1.45 g/cm. cube
How to identify Polyacrylate (organic glass). Transparent, fragile material. It burns with a bluish-luminous flame with a slight crackle. The smoke has a sharp fruity smell (of ether). Easily soluble in dichloroethane.
How to identify Polyamide (PA). The material has excellent oil-petrol resistance and resistance to hydrocarbon products, which provide a wide application of PA in the automotive and oil industries (manufacturing of gears, artificial fibers ...). Polyamide has a relatively high moisture absorption, which limits its use in humid environments for the manufacture of critical products. Burns with a bluish flame. When burning, it swells, “puffs”, forms burning streaks. Smoke with the smell of burning hair. Solidified droplets are very hard and brittle. Polyamides are soluble in phenol solution, concentrated sulfuric acid. Density: 1.1-1.13 g/cm. cube Drowning in water.
How to identify Polyurethane. The main area of application is shoe soles. Very flexible and elastic material (at room temperature). In the cold - fragile. Burns with a smoky, glowing flame. At the base, the flame is blue. When burning, burning droplets-streaks are formed. After cooling, these drops are a sticky, greasy substance to the touch. Polyurethane is soluble in glacial acetic acid.
How to identify Plastic ABC. All combustion properties are similar to polystyrene. It is quite difficult to distinguish from polystyrene. ABS plastic is stronger, tougher and more viscous. Unlike polystyrene, it is more resistant to gasoline.
How to determine Fluoroplast-3. It is used in the form of suspensions for applying anti-corrosion coatings. Not flammable, charred when heated. When removed from the flame, it immediately extinguishes. Density: 2.09-2.16 g / cm3
How to determine Fluoroplast-4. Non-porous white material, slightly translucent, with a smooth, slippery surface. One of the best dielectrics! Not combustible, melts when heated. It is insoluble in virtually all solvents. The most resistant of all known materials. Density: 2.12-2.28 g / cm3 (depending on the degree of crystallinity - 40-89%).

Physical and chemical properties of plastic waste plastic waste in relation to alkalis
ANY plastic releases chemicals of varying degrees of danger into the contents of the bottle.
Wear resistance - a characteristic of a material that demonstrates its resistance to wear under various operating conditions; both speed and intensity of wear loads are taken into account.
Wear resistance is determined by a number of factors:
- material structure;
- composition of the material;
- basic parameters of hardness and roughness;
- anticipated and actual operating conditions.
Wear-resistant plastic initially has good resistance to physical damage, in many cases significantly exceeding those of steel products.
Often, to achieve the required level, you have to take additional measures, for example, the use of an additional wear-resistant coating. This allows you to seriously improve performance, but complicates production, increases the cost of the finished product.
Wear-resistant plastic is actively used in mechanical engineering. In particular, polyamide gears are becoming increasingly popular, replacing steel counterparts in many technical units that require high wear of the parts involved due to constant load.
Our range includes such types of wear-resistant plastic as:
- especially durable types.
Plastic, or plastic, is an organic material based on macromolecular compounds - polymers. The opinion that plastic is a more durable and high-quality material than plastic is erroneous. The difference between these concepts is only in their name. Types of plastic, its types, classification, labeling, areas of use are huge.
What it is
Plastic products have firmly entered our lives. Particularly widely used are plastics based. The manufacturing process is the transition of a material under the influence of heat and pressure from a fluid state to a solid state. The development of plastics began with the use of natural ingredients. Later they were replaced with chemically modified materials. Now, for the manufacture of plastics, fully synthetic molecules are used - polyethylene, polyvinyl chloride, epoxy. And the secret of popularity is as follows: ease of production, practicality, affordable price.
Main characteristics
The types and properties of plastic, its weldability primarily depend on the polymer from which it is made. All kinds of additives, additives, stabilizers, pigments, organic and inorganic fibers also affect the physical and mechanical characteristics of plastics. Some, for example, protect plastic from ultraviolet radiation.
The material is mostly white or transparent. With the addition of dyes, plastic can acquire any color. In this way, a mirror plastic can be produced. Most plastics are multicomponent and composite materials. Plastic has a low density. Resistant to acids and alkalis. It has low thermal and electrical conductivity. Most species are easy to process. This allows the production of molded products from raw materials, as well as the use of sheet plastic, combining thermoforming with mechanical processing.
Areas of use for plastics
The scope of plastics is huge. Starting with use in shipbuilding, aircraft building, ending with agriculture, medicine and everyday life. The types of plastic are amazing. Photos show only a small fraction of the products:
- Plastics are widely used in the production of parts for large vehicles, as well as for interior trim.
- The development of agriculture implies the use of plastic in land reclamation, the manufacture of packaging materials for the storage of agricultural products, the construction of film shelters and greenhouses.
- Many medical instruments, special utensils, medicine packaging are made of
- In construction, these are metal-plastic pipes and fittings. An alternative to glass is designs made of light or transparent plastics.
- In everyday life - the use of all kinds of containers, bottles, packages, children's toys and much more.
transparent plastic
Plastic types include thermoplastic PVC, which is mainly used for sheet materials. It is used in construction, outdoor advertising and other fields. A type of sheet material is transparent plastic. Depending on the light transmission capacity, the material can either block or transmit some of the ultraviolet rays. It can be transparent and translucent colored sheet materials.
Types of transparent plastic are represented by plexiglass, polycarbonate, polystyrene, polyester glass, transparent PVC sheets. First of all, they are impact resistant. More durable is polycarbonate. Polyester glass is considered the most elastic. The light transmission capacity is higher for plexiglass, it is the most transparent and clear, it is well processed. Transparent plastic is used for glazing windows, goggles and police shields, making plastic bottles. Transparent plastic can have different shades.
Plastic facades
Types of plastic for facades are divided into sheet and roll. The hard and solid sheet of material is high pressure plastic. Cold or medium pressure roll plastic is of lower quality and cheaper than sheet plastic. This material in rolls resembles It is used, among other things, in the manufacture of furniture facades.
Types of plastic for the kitchen have a different basis. Some are made on the basis of chipboard, and it is cheaper than the base of MDF. Sheet plastic is thermally stable, it is not subject to scratches, chips, impacts, does not deform, does not fade or fade. The material does not peel off from the base, is not afraid of moisture, and is easy to clean. The disadvantage of facade details is that they can only be even, without milling, and smooth in texture.
Finishing
Today, plastic remains a popular building material. Mostly different types of plastic are used for office decoration. But in the presence of imagination and with a competent design, such material will look great in the decoration of the apartment. Plastic can be sheathed on any surface, whether it be a ceiling or walls. The main type of material for ceiling surfaces is widely varied. Separate elements are interconnected with the help of stiffening ribs (the panel has a groove on one side, and a spike on the other). The material is light and safe. Convenient for transportation and easy to assemble.
Plastic, having moisture resistance, is used in bathrooms and when facing balconies. It is used for arranging slopes and finishing ceilings. With a successful and competent choice of plastic, you get an excellent entrance hall. Plastic panels can be matte or glossy, imitate wood or stone.
Advantages and disadvantages
In some areas of human activity, many types of plastic are approved for use by the Ministry of Health:
- Weather resistant material. It has good electrical insulation and
- Easy to process. Easy to weld and glue. You can cut and form the necessary structures.
- The material is inexpensive. For a long time retains its original appearance. Not afraid of moisture.
- Has a rich color range. Sheet transparent plastic possesses shock-resistant and fire-resistant properties. From it you can get products of various shapes.
- resistant to temperature changes. When finishing the room, it plays the role of a sound and heat insulator. Suitable for arranging awnings, street signs, signs, advertising objects.
Like any material, plastic has some disadvantages:
- Resistant to many organic solvents.
- Plastic elements can be deformed under heavy loads or high temperatures.
