|---|
| NANCAR® 4580 is a high acrylonitrile butadiene copolymer with excellent oil resistance. It is polymerized at low temperature and contains sufficient antioxidant for normal aging conditions. It has fast curing rate, low mold fouling and superior resilience properties. It has good processing characteristics in compounds where flow and knitting are desired and is especially valuable in high durometer compounds. NANCAR® 4580 provides good processing and building tack. It is suggested for use in molded goods, friction stock and similar applications.&& |
