Popular Science on Insulation & Sheath Materials of Wires & Cables

May 20, 2026

Insulation and outer sheath are core protective structures of wires and cables, determining temperature resistance, waterproof performance, wear resistance and anti aging performance, which are also key assessment items for overseas export compliance certifications.

 

  • PVC: Cost effective and easy to process, widely used in ordinary power cords and household wiring cables, meeting basic RoHS environmental requirements.
  • TPE: Flexible, highly elastic, bending resistant, eco-friendly and odor free with excellent anti-aging performance. It is the mainstream export special material for data cables, retractable charging cables and flexible wires.
  • XLPE: High temperature resistant, strong insulation and high voltage resistant, mainly used in industrial and power transmission cables.
  • Rubber: Outstanding performance in wear resistance, oil resistance and cold resistance, suitable for special cables for outdoor environments and mechanical equipment.

 

With the upgrading of global environmental requirements, the demand for eco-friendly flexible TPE cables keeps growing in the digital accessory cable export market, which is more favored by European and American buyers.
