What are the cable sheath materials?

As the outer layer of the wire, the role and importance of the wire sheath are self-evident

Cable sheath raw material: PE

Due to its excellent electrical insulation function and excellent processing function, polyethylene is commonly used as a coating raw material for wires and cables, focusing on the insulation layer and sheath layer of wires and cables.

Excellent electrical functionality and extremely high insulation resistance. Polyethylene may be tough and equally hard, but low-density PE (LDPE) is more flexible, moisture-resistant, etc. Properly formulated PE has excellent weather resistance

Cable sheath raw material: PVC

The cable material is polyvinyl chloride as the basic resin, adding stabilizers, plasticizers and calcium carbonate and other inorganic fillers, additives and smoothing agents and other additives, and mixing and kneading and extruding particles from beginning to end.

PVC may be formulated for use in a variety of environments and uses. It has low cost, good flexibility, equal strength, and fire/oil retardant raw materials.

Cable sheath raw material: PUR

PUR cable is one of the cables. PUR cable raw materials have the advantage of oil resistance and wear resistance. And PVC is made of ordinary raw materials. In the cable industry in previous years, the identity of polyurethane has become increasingly important, at a certain temperature, the mechanical properties of the raw material are similar to rubber, thermoplastic and elastic fusion to obtain TPE thermoplastic elastomer.
