Nipol DN401LL 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. Very good low-temperature flexibility and low viscosity for superior processing properties. Nipol DN401LL is a copolymer of butadiene and acrylonitrile whereby, the extremely low acrylonitrile content is designed for the maximum in low temperature performance. Butadiene and acrylonitrile copolymer. Possesses low acrylonitrile content and low viscosity. Provides very good low-temperature flexibility. Used in adhesives.
