Caprolon: technical characteristics, features, scope, variety of material

Caprolon, whose technical characteristics will be described in the article, is the Russian name of one of the popular polyamides - polycaproamide. On sale today you can find more and analogs of caprolon, which today is also quite common.

general description

The material mentioned above is relatively new, it has been known since 1980. Has unique properties, has a high degree of durability and strength. If it is a qualitative caprolon, then it can be outdoors for several years, while the material will not lose its mechanical and physical characteristics, will not require protection from the influence of the external environment and ultraviolet.

Material Features

Caprolon, the technical characteristics of which should be known to you, if you plan to purchase it, is resistant to:

• chemical substances;
• Ethers;
• Solvents;
• Diluted acids;
• Alcohols.

Caprolon dissolves in formic and concentrated sulfuric acids, as well as in fluorinated alcohols. Among the basic properties of this material is a low coefficient of friction, this makes it possible to use it in the manufacture of bearings and other rubbing parts during operation. However, this option is not the only way to use caprolon in the field of industry.

Scope of use

Caprolon, whose technical characteristics are quite unique, is used instead of metals. The material is 6 or even 7 times lighter than steel, this indicates that the products have a low weight and high strength. Caprolon is used for the manufacture of bearings that are resistant to corrosion, are characterized by abrasion resistance, low friction coefficient, among other things, these parts have a self-lubricating effect.

Caprolon is used to produce gears, pump blades, lobsters, various housings, as well as rollers, which form the basis of conveyor belts. Sometimes this material also produces cutting boards, which are convenient to use in the meat industry.

For reference

The caprolon described in the article, the technical characteristics of which will be of interest to each consumer, can reduce the wear of products, increasing their service life by 1.5 times. The laboriousness of the manufacturing process is 35% less, while the final cost is almost 0.5 times lower than in the case of bronze and steel analogues.

Varieties of caprolon: sheet material

The most popular version of this material is a sheet caprolon, which is a blank used to produce different parts, namely:

• Bushings;
• Loose leaves;
• Flanges;
• Rings.

The material is usually in the form of a square with a side of 1000 mm, while the thickness can vary from 6 to 250 mm. However, these parameters can be changed. Storage of the material should be carried out in rooms with low humidity conditions. Caprolon, technical characteristics and features of which are described in the article, should be used with extreme caution, which is due to its elasticity, smoothness and slipperiness. Therefore, masters should observe safety techniques when there is a need to hit the surface with a sledge hammer or hammer. Do this only after the sheet can be fixed. Experts advise working with gloves, as hands can be damaged with sharp edges.

Processing of sheet caprolon is carried out on metalworking machines, but some recommendations should be taken into account. When machining it is necessary to provide a heat sink, the material has a low level of melting point. If complex processing is required, it should be borne in mind that the material may become cracked, so it is recommended to divide the work into several stages.

Specifications

Caprolon, the properties and application of which must be known to the consumer before making a purchase, has a density ranging from 1150 to 1160 kg / m³. The operating temperature varies from -40 to +70 ° C, while the melting point reaches 250 ° C. It is important to know also the average coefficient of thermal linear expansion, which is 0.000098, when the temperature varies from 0 to 50 ° C.

Experts are sometimes interested in a parameter such as Brinell hardness, which can not be lower than 130 HB. If it is a leaf caprolon, then the limit of its strength when bending is 80 MPa or more. The compressive strength is 90 MPa or more. At break, the relative elongation is 10%, and the thermal conductivity coefficient is 0.29 at 20 ° C. Caprolon, the technical characteristics, the temperature of which is mentioned in the article, has an electrical strength in the range from 30 to 35 kV / mm.

The main types of material

Caprolon graphite filled, the technical characteristics of which allow it to be used in industry, has a coefficient of friction, which is 3 times lower in comparison with the polyamide of the sixth grade. On durability, this type of material is superior to other brands of caprolon. Among them we can distinguish:

• Polyamide 6;
• PA6-MG is a material modified with graphite;
• PA6-MDM is a molybdenum disulfide modified.

Polyamide 6 can be manufactured by extrusion or by casting technology. In the first case, the material is quite strong and has a high viscosity and reduced wear resistance. If we are talking about polyamide, made by the method of casting, then you have the most popular caprolon in Russia, which has antifriction qualities and is easy to process. This material is completely harmless to human health and can be used even in the food industry.

If a solid lubricant is added to the polyamide 6, it will be possible to obtain a material with increased slip values, which makes it possible to use it in the manufacture of parts and assemblies where permanent lubrication is required. Today, caprolon is quite popular, technical characteristics, which are of interest to many consumers. But this material is made according to specifications 2224-036-00203803-2012 and has a color from white to cream. If before you are varieties PA6-MG and PA6-MDM, then the color can be gray or black. However, the sixth grade caprolon is made using pigments, as a result, it is possible to obtain a material of different colors. The main brands of this material are designated by two letters - "A" and "B"; in the first case, caprolon is used for the manufacture of parts for aircraft construction, whereas in the second case for structural engineering components.

Conclusion

Caprolon is resistant to the effects not only of hydrocarbons and ketones, but also of weak acids and alkalis. Under normal conditions, the material is not toxic, does not have harmful effects on the human body and animals. During the mechanical processing of products, decomposition does not occur, no harmful substances are released. When the material is exposed to temperatures above 300 ° C, the caprolon begins to decompose, with ammonia and carbon monoxide being released.
