    Polyethylene [—CH2 — CH2—] n, white thermoplastic polymer. In industry, it is obtained by polymerizing ethylene at high pressure (low density P.) and low or medium pressure (high density P.). The structure and properties of P. are determined by the method of its preparation.

    The average molecular weight of the most common brands is 30-800 thousand; the degree of crystallinity and density at 20 ° C are, respectively, 50% and 0.918-0.930 g / cm3 for low-density polymers and 75-90% and 0.955-0.968 g / cm3 for high-density polymers. With an increase in density, the hardness, flexural modulus, yield strength, and chemical resistance increase. The item combines high tensile strength (10–45 MN / m2, or 100–450 kgf / cm2) with elasticity (elongation at break of 500–1000%).

    It has good electrical insulating properties (for example, the tangent of the dielectric loss angle is 2 × 10-4-4 × 10-4 at temperatures from –120 to 120 ° C and a frequency of 10–50 kHz). Resistant to alkalis of any concentration, organic acids, concentrated hydrochloric and hydrofluoric acids; destroyed by nitric acid, chlorine and fluorine; above 80 ° C dissolves in aliphatic and aromatic hydrocarbons and their halogen derivatives; relatively resistant to radioactive radiation; harmless; operating temperature range from -80 ¸ -120 to 60 ¸ 100 ° C.
