Nipol HR765 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. Polymerization-bound stabilizer. Excellent resistance to deterioration from fluid extraction. Medium Mooney/Medium Low ACN for balance of properties in high/low-temperature service. High performance injection molding of precision dynamic abrasion seals. Excellent resistance to dynamic fatigue. Fast cure rate, high resilience and low water swell. Nipol HR765A is a cold, fatty acid, butadiene-acrylonitirile copolymer. Butadiene-acrylonitrile copolymer. Possesses medium-low ACN and medium mooney for good mold flow. Provides balance of properties in high/low-temperature service, very good resistance to deterioration from fluid extraction, fast cure rate, high resilience, low water swell and very good resistance to dynamic fatigue. Used in adhesives.
