Heat resistant silicone rubber cable
Heat-resistant silicone rubber insulated cables and heat-resistant silicone rubber sheath flexible cable. Silicone rubber has excellent physical and mechanical properties and electrical insulation properties, resistance to atmospheric aging, smelly endowment, light aging resistant, flame retardant, radiation resistant, oil resistant, is to use one of the highest temperature elastomer material, widely used in Marine cable, aviation wire leads by now, motor, heating cable and other cable insulation and sheath. Heat-resistant silicone rubber cable is suitable for power generation, metallurgy and chemical industry such as high temperature environment and requires heat resistant and corrosion occasion of portable electric equipment such as power, control and signal connection.
