Product Description:
This product is made of polyether polyurethane elastomer as the base material, adding high-efficiency flame retardant and other processing aids, and is made by mixing, plasticizing and granulating. It has excellent performance such as halogen-free, high flame retardant grade, high resilience, hydrolysis resistance, heat resistance, weather resistance, oil resistance, etc., and can add matte, frosted and other effects according to customer needs; no precipitation pollution, in line with Rohs and other relevant requirements.
Application Field:
suitable for 3.0\5.0\8.0 optical cable outer sheath.
