| About |
|---|
| NANCAR® 3345 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 low Mooney viscosity, superior processing characteristics, fast curing rate, low mold fouling, superior resilience properties and superior flowability. NANCAR® 3345 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, roll covers and sponge products.&& |
