1.product characteristics
This product is a kind of saturated thermoplastic elastomer with irregular structure, almost no crystal. It features lower plasticizing temperature and Mooney viscosity, fine processing property, heat resistance, weatherability, oil resistance, flame retardancy, chemical resistance and ozone resistance and so on. It can not only act as impact modifier of hard PVC products to largely produce plastic doors & windows and pipes but also act as special rubber to substitute chloroprene rubber and to produce wires, cables, rubber hose and adhesive tape.

3.use
The product is mainly used for special synthetic rubber. In addition, it can act as modifier and solubilizer of general-purposed synthetic rubber. It is widely used in such fields as wires and cables (cables for coal mine and specified wires in standard of UL and VDE etc.), hydraulic rubber hose, rubber hose for vehicles, adhesive tape, adhesive board, PVC profiles, pipe modification, magnetic materials and ABS modification and so on.
