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.
