1. Wires for heat-resistant materials: Refers to the insulation and protective sleeve material. The resin has heat resistance. The main varieties are: polyurethane (up to 155 ° C), polyester (up to 135 ° C), polyvinylidene fluoride ( Insulation or jacket material of 150 ° C) and nylon (up to 115 ° C).
2. Ordinary materials achieve heat resistance through various methods of modification: heat-resistant modification of rubber materials (up to 135 ° C), modification of polyvinyl fluoride wires (90 to 120 ° C), modification of polyethylene cables Sexuality (105~150°C).
