NANCAR 1051 NBR

NANCAR 1051 is a high acrylonitrile butadiene copolymer with excellent oil
        resistance. It is polymerized at low temperature and contains sufficient
antoxidant for normal aging conditions. It has good processing characteristics in compounds where flow and knitting are desired and is especially valuable in high durometer compounds.

 
NANCAR 1051 provides good processing and building tack. It is suggested for
        use in molded goods, friction stock and sililar application.
