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 dielectric properties, resistance to low temperature and environmental stress cracking properties. It is suitable for the outer protective layer of communication optical cable, signal cable and control cable.
