Polyethylene is a thermoplastic resin produced by polymerization of ethylene. Polyethylene is odorless, non-toxic, feel like wax, has excellent low temperature resistance, the lowest temperature can reach -100°C, good chemical stability, can withstand most acid and alkali erosion, but can not contact with acid with oxidizing properties. Insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation.
Superior Characteristic
(1) Excellent electrical performance. Its insulation resistance and high electric strength, as a communication cable insulation material, is almost an ideal medium.
(2) Good mechanical properties, flexible, and strong, good tolerance.
(3) Good heat aging resistance, low temperature cold resistance and chemical stability.
(4) Good water resistance, low moisture absorption, immersion in water insulation resistance generally does not decline.
(5) As a non-polar material, the air permeability is large, low density polyethylene is the most excellent in all kinds of plastics.
(6) Light specific gravity, its specific gravity is less than 1. High pressure polyethylene is particularly prominent, about 0.929/cm3, low pressure polyethylene although its density is larger, it is only about 0.94g/cm3.
(7) Has good processing performance, easy to melt plasticizing, and not easy to decompose, easy to form cooling.
(8) the wire and cable made with it is light in weight, convenient in use and easy in joint.
