    Polychloroprene Rubber CR322

    CR322 Chloroprene rubber is kind of sulfur and X
    anthogen mixture modified Poly-chloroprene rubber.It is medium rate Crystallization polymer,Non polluted.Its density 1.23 .Appearance to Light yellow Clips.It has high tear resistance and anti-flame class performance ,very suitable for conveyor belt,V belt,cable sheaths, Widely used in diving suit and most rubber products such as Rubber seal,dust cover,cable sheaths,rubber hose etc.  


    • High tear resistance and strength 
    • Weatherability ,Resistance to Ozone,Anti Aging
    • Heat resisting and Anti-flame
    • Special cohesiveness ,can be easy process 


    • Electrical wiring and cable sheath
    • Automotive componets
    • Conveyor belts,V belts,Timing belts
    • Rubber hose
    • Other general rubber industrial products. 

    It is light yellow color chlips and does not contain mechanical impurities other than talcum powder.
