Wire and Cable Extrusion

The extrusion process is a key technique for applying a polymer coating to wires and cables. During this procedure, the wire or cable is uniformly drawn through a crosshead die and receives a coating of molten plastic. This method is prevalent in the production of wires and cables for telecommunications, electrical, and electronics sectors. For additional coating layers, a dual-extruder setup may be employed.

Polymers selected for wire and cable (W&C) coating via extrusion are chosen for their:

Flexibility
Electrical insulation capabilities
Flame retardance
Abrasion resistance
Longevity

Common polymers used in W&C coatings include:

Polyethylene (PE)
Polyvinylchloride (PVC)
Polyamide (PA)
Polybutylene terephthalate (PBT)
Thermoplastic elastomers (TPE)
Ethylene propylene copolymers (EPC)
Polypropylene (PP)
Fluoropolymers (FP)

These materials are favored in wire and cable applications for their robust properties, ensuring performance and safety in a variety of uses.
