Our company mainly used as the impact resistant modifier of PVC. At present, it takes 95% share of the impact resistant modifier market of domestic PVC. The additive shares of135A type CPE as the impact resistant modifier of PVC profile shapes is 9~ 12; the shares as the impact resistant modifier of PVC water feeding pipe and other liquid transfer pipe under pressure is 4~ 6; this can effectively improve the low temperature resistant impact property of PVC product. In addition, H135 type CPE is widely added into the products including PVC plate, sheet, calcium-plastic box, case of household appliances and electrical appliance fittings to improve the mechanical property and electrical property. CPE can be compatible and use with most plastics and rubbers simultaneously. The polymer crossblend system with bad compatibility can take CPE as bulk filler. The rubbers used together with CPE include caoutchouc, butadiene styrene rubber, ethylene propylene diene copolymer, polyurethane rubber, acrylonitrile butadiene rubber, neoprene and chlorosulfonated polyethylene etc. The plastics used together with CPE include PVC, PE, PP, EVA and PA etc, which greatly improve the low temperature resistant impact property and increase flame resistance, oil and aging resistance, corrosion resistance and insulatibity.
