Chlorinated Polyethylene (CM)
Chlorinated Polyethylene(CM)
Properties
Chlorinated Polyethylene CM-240M is a kind of CPE for rubber. 40% chlorine content, good flame retardancy, oil resistance and high Mooney viscosity. Chlorinated Polyethylene CM-240M is used for oil resistant products, such as mining cable sheath and oil resistant hoses.
Chlorinated Polyethylene CM-235MPT is a kind of CPE for rubber. Medium molecular weight, Mooney viscosity between 70 and 80, good mechanical property, good appearance and good processibility. Chlorinated
Polyethylene CM-235MPT has fine surface and high extruding speed when used for wires, cables and hoses.
Chlorinated Polyethylene CM-235HPT is a kind of CPE for rubber. Highest molecular weight, relatively narrow molecular weight distribution, highest Mooney viscosity and best physical performances. Chlorinated Polyethylene CM-235HPT is used for production of high performance rubber product.
