2 characteristics of heat-resistant wire and cable

1. Heat-resistant materials for wire and cable: heat-resistant materials for wire and cable is the insulation and sheath material body resin with heat-resistant properties, the main varieties are: polyurethane (up to 155 ° C level), polyester (up to 135 ° C), polyvinylidene fluoride (150 ° C) and nylon (up to 115 ° C) of the insulating or sheathing materials. Commonly used in communications, automotive, electrical machinery, construction and other industries. 2. Common cable materials through various ways of modification to achieve heat resistance: heat-resistant modification of rubber materials: rubber materials because of its poor heat resistance, and thus improve the working temperature of the margin is small, ordinary rubber filled with more heat stabilizers and crosslinking treatment to reach 90 ℃, and therefore can not be called heat-resistant cable, such as styrene butadiene rubber, neoprene rubber, chlorosulfonation, etc.. Polyethylene, etc. Mainly used in rubber insulated mobile flexible wires, rubber insulated flexible power cables and control cables, etc.; PVC cable modification: ordinary PVC cable operating temperature of 70 ℃, PVC cable materials, high mixability, so that its modification becomes possible, the use of a large number of heat stabilizers, PVC can be heat-resistant from 70 ℃ up to 90 ℃ or 105 ℃, thus greatly expanding the PVC this The applicability of old-fashioned materials; polyethylene cable modification: polyethylene material plasticity is better, but the filler is poor, and thus can not be filled with heat stabilizer method to improve the heat-resistant temperature. Polyethylene cable through the DCP dry chemical crosslinking and silane warm water crosslinking will increase the working temperature to 90 ℃, the former for medium and high voltage power cables, the latter for low voltage cables.-3、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
