Nipol 35-8 Acrylonitrile / Butadiene polymer 9003-18-3 Zeon Chemical Rubber - Elastomer >> Butadiene-acrylonitrile / Nitrile rubber, NBR ADHESIVE Zeon's wide range of NBR elastomers are generally catagorized by the ACN and Mooney Viscosity. The higher ACN levels have better chemical resistance but poorer low temperature properities. The lower ACN levels will have higher swell in oils and fuels, but improved low temperature flexibility. General-purpose, high Mooney viscosity nitrile rubber. Combines exceptional physical properties and outstanding oil resistance. Recommended for critical industrial and automotive extruded goods. Butadiene and acrylonitrile copolymer. Possesses high mooney viscosity. Provides very good physical properties and very high oil resistance. Used in adhesives for critical industrial and automotive extruded goods.
