Introduction to inner plastic and outer fiber
It is made of silicone rubber extruded into a tube, then coated with woven glass fiber and treated with silicone resin at high temperature. With excellent insulation and temperature protection, it is also widely used in H& Class N automotive, shipbuilding, electric motors, household appliances, electric heating equipment, special lamps and other insulation protection.
