NANCAR®
3365 is
a medium high acrylonitrile butadiene copolymer with good oil resistance. It is
polymerized at low temperature and contains sufficient antioxidant for normal
aging conditions. It has superior processing characteristics, fast curing rate,
low mold fouling and superior resilience properties.
NANCAR®
3365 is
an excellent multi-purpose nitrile elastomer. It may be blended with vinyl
resins to produce smooth extrusions and nerve-free sheets. Suggested
applications include those in fuel hoses, packings, gaskets, oil seals, other
car parts, oil resistant belts, footwear and roll covers.
