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.
