Description of products
This product is made of polyethylene resin as the main raw material, adding carbon black, lubricant and other additives, by mixing, plasticizing and granulating. This material has excellent electrical properties, resistance to low temperature and environmental stress cracking properties. It can be widely used in communication cable, signal cable, control cable and power cable.
