This material is a synthetic polymer with excellent physical and chemical properties. Comparing this brand of polyamide with others, the following distinctive properties can be identified:
- – low moisture absorption coefficient;
- – high electrical insulating properties;
- – excellent dimensional stability of the material;
- – low susceptibility to temperature deformation;
- – high antifriction properties;
- – high oil? and gasoline resistance.
Polyamide conforms to the chemical formula ([-NH-(CH2)6-NH-CO-(CH2)8-CO-]n).
Liteva polyamide 610 Intended for the manufacture of injection molding of various products for structural and electrical insulating purposes.
Molded polyamide products PA 610 can be operated without reducing mechanical properties in the temperature range from minus 60 to plus 70 degrees Celsius, including electrical insulating products operated at low and medium frequencies.
Glass-filled polyamide PA 610 has a number of improved properties. Its chemical inertness to many oils and alcohols, as well as its elasticity and elasticity at low temperatures, makes it possible to produce some of the highest quality parts from it. Glass-filled polyamides are characterized by increased strength and resistance to impact loads. Glass-filled polyamides are also characterized by good dielectric properties. Glass-filled polyamide is used to make parts of precision instruments, housings of power tools, such as drills, casings of small-sized pumps, cam disks, bearing cages, needle roller bearings, load-bearing parts of transformers, etc.
Soap filled polyamide PA 610 has increased anti-friction and electrical insulating properties. Compared to glass-filled polyamide, soap-filled polyamide has a higher impact strength, this is due to the low adhesion of glass fiber. Soap filled polyamide 610 has increased dimensional stability.
Graphite-filled polyamide PA 610 has even higher anti-friction properties.

| Fire resistance | Polyamide 610. Polyamide 610 is a polycondensation product of SG salt. Molded polyamide 610 is intended for injection molding of various products for structural and electrical insulating purposes. Products made from injection molded polyamide 610 can be used without reducing mechanical properties in the temperature range from minus 60 to plus 70°C, including electrical insulating products operated at low and medium frequencies. Technical characteristics of polyamide PA 610 L. GOST 10589-87
For products that do not experience mechanical stress during operation, the upper temperature limit can be increased to plus 100°C. Molded polyamide 610 is resistant to hydrocarbons, organic solvents, oils and alkalis. Molded polyamide 610 is resistant to solar radiation. Polyamide copolymers. One of the common methods for modifying polyamides is the synthesis of copolymers. Usually, for this purpose, a joint polycondensation of caprolactam, AG salt, and dodecalactam, taken in various ratios, is carried out. The most important are: Polyamide copolymer AK 80/20. Molding copolymer of polyamide AK 80/20 is intended for the manufacture by injection molding of various products for structural purposes used in mechanical engineering, electrical industry, instrument making, etc. The temperature range of operation of products is from minus 50 to plus 70 degrees Celsius. Polyamide copolymer is resistant to hydrocarbons, organic solvents, oils, diluted and concentrated alkali solutions. It dissolves in concentrated mineral acids, formic and acetic acids, and in phenols. Molded polyamide copolymers Molded polyamide copolymers are intended for the production of injection molded various products for structural purposes, used in mechanical engineering, electrical industry, instrument making and other sectors of the national economy as substitutes for non-ferrous metals. The operating temperature range for products made from injection molded polyamide copolymers is from minus 50 to plus 70°C. Molded polyamide copolymers are resistant to hydrocarbons, organic solvents, oils, diluted and concentrated alkali solutions. They dissolve in concentrated mineral acids, formic and acetic acid, and in phenols. Physico-mechanical properties of injection molded polyamide copolymers
