Chloroprene Rubber (CR) is a polymer of chloroprene monomer byemulsion polymerization. Since this rubber molecules containingchlorine atoms, compared with other general-purpose rubber: it hasa lot of advantages, such as excellent antioxidant, anti-ozone,non-flammable, self-extinguishing after the fire, resistant to oil,solvent, acid and anti-aging, gas tightness; Its physical andmechanical properties are better than natural rubber, so it can beused as general rubber, as well as special rubber. The maindrawbacks include poor cold resistance, high specific gravity, highcost, electrical insulation is not good, while processing easy tostick to roll, scorch and stick to mode. Besides, t the raw rubberis not stable and defficult to store. Operating temperature range:about -45 ° C to 100 ° C Mainly used in manufacturing productswhich require high resistance to ozone and aging, such as cableshieath and all kinds of shelter, protective cover; It''s also usedin oil and chemical resistant products like hose, belt and chemicallining; the flame-retardant products like underground mining rubberproducts; And a variety of molded products, seals, pads, binders,and so on.
