Product Model: PFEBS61D553
This product is made of high-purity polypropylene resin as the base material, adding high-quality and efficient flame retardants, antioxidants and other processing aids, and is made by mixing, plasticizing and granulating. It has excellent mechanical and physical properties, electrical properties, flame retardant properties, and has high heat resistance and other characteristics. No precipitation pollution, in line with the relevant requirements of Rohs, etc., easy to extrude and process.
Product Application: Suitable for the production of 0.35mm²~6mm² automotive cables with ISO19642/ISO 6722/JASO D611 and other standards.
