| SlLVER® Modified Polyolefin includes modified polyethylene and modified polypropylene. Modified polyethylene is mainly applied to cable jacket. Black polyethylene compound is composed of polyethylene resin,carbon black, antioxidantand so on. Black polyehylene compound is applied to communication cable,contoll cable,signal cable,power cable,opticalcable and submarine cable. It conforms to GB15065-94 Standard. Modified PP including flame resistant, glass fiber andmineral reinforced and weather—resistant, is widely applied in electronic & electrical appliances, household appliances, autoaccessories, lightings, mechanical components and sockets, and so on. In addition, we develop new products according to customer’s specific requirements. Characteristics: extrusion grade LDPE+HDPE Applications: cable jacket&& |
