One. Glue material generally has PVC, PE, PP and other materials, according to different characteristics of wire manufacturers will generally choose not easy to burn, aging resistance, oil resistance PVC as the outer cover of the cable.

1 PVC(polyvinyl chloride) is not easy to burn, aging resistance, oil resistance, chemical resistance, impact resistance, easy to color characteristics, so the wire processing plant, will generally choose PVC as the wire and cable insulation sheath. However, due to the high dielectric constant, it is generally only used as the insulation material of low-voltage cable and control cable, with the lowest operating temperature of -40 ° c and the high temperature resistance of up to 105 ° c.

2.PE(polyethylene) processing melting point range is 132~1350℃, ignition temperature is 3400℃, natural temperature is 3900℃, so in the process of wire harness processing, PE is usually selected as the material of forming inner membrane.

3.PP(polypropylene) has excellent mechanical strength, the highest softening temperature in thermoplasticity, low temperature resistance, aging resistance, general wire harnessprocessing plant will choose a small number of external mold forming.

Main cable transmission signal conductors, according to the characteristics of different metal, usually using bare copper wire, tin copper wire, silver-plated copper wire, etc., according to the type of wire is different, the metal conductor occupies proportion each are not identical, the copper wire cost proportion accounted for the biggest, so the cost of the wire will change as the copper price.
