Nitrile Butadiene Rubber (NBR), 65-75 °IRHD. Ultra-Low acrylonitrile (ACN) content. Copolymer of acrylonitrile and butadiene. To meet ASTM D2000/SAE J200 line call-out: MBF710, B34, F19. Specifically formulated for use in pure air systems. The low acrylonitrile content of this compound provides excellent resistance to mineral oil, alcohol, paraffin and low-aromatic petrol in sub-zero temperature applications. Not recommended for use with acetone, benzene, chlorinated solvents or high-aromatic petrol. Good water resistance but poor against ozone and weather. |
