PE cable sheathing material-specifically designed for polyethylene cable jackets-is a thermoplastic resin produced through the polymerization of ethylene monomers. It is an industrial material formulated with additives (such as antioxidants, UV absorbers, and carbon black) and intended for the extrusion of the outermost protective layer of wires and cables.
As the outermost layer of a cable, the sheath serves several key functions:
Protecting the cable's internal structure from mechanical damage during installation and operation;
Providing protection against moisture, chemical corrosion, ultraviolet (UV) radiation, and ozone;
Working in conjunction with internal reinforcement and protective elements to provide an appropriate level of protection.
