Nipol HR665 Butadiene-acrylonitrile copolymer 43063-09-8 Zeon Chemical Rubber - Elastomer >> Butadiene-acrylonitrile / Nitrile rubber, NBR ADHESIVE Nipol High Performance Terpolymers contain an anitoxidant that is polymerized into the backbone of the polymer. This prevents extraction of the antioxidant from oils and fuels and makes this an excellent choice for long life applications where fluid exposure will occur. Nipol HR665 is a cold, fatty acid, butadiene-acrylonitrile copolymer made with built-in antioxidant. Polymerization-bound stabilizer. Excellent resistance to deterioration from fluid extraction. Medium Mooney for maximum dynamic abrasion resistance at high temperatures. Fast cure rate, high resilience. Low water swell. Excellent resistance to dynamic fatigue. Butadiene-acrylonitrile copolymer with built-in antioxidant. Possesses medium mooney for good mold flow. Provides very good resistance to deterioration from fluid extraction, fast cure rate, high resilience, low water swell, very good resistance to dynamic fatigue and dynamic abrasion even at high temperatures. Used in adhesives.
