Nipol 40-5 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. Special-purpose, high Mooney viscosity nitrile rubber. Combines excellent physical properties and processability with very high oil resistance. Recommended for oil fields parts and other applications requiring high oil resistance. Special-purpose, intermediate-viscosity nitrile rubber. Combines excellent physical properties and processability with very high oil resistance. Recommended for oilfield parts and other applications requiring high oil resistance. Butadiene and acrylonitrile copolymer. Possesses intermediate-high mooney viscosity. Provides very good physical properties and processability, and very high oil resistance. Used in adhesives.
