Precision Polymer N70L

About
Nitrile Butadiene Rubber (NBR), 70 IRHD. Low- Med acrylonitrile (ACN) content. Copolymer of acrylonitrile and butadiene. To meet: ASTM D2000/SAE J200 line call-out: M5BG710, A14, B14, EO14, EO34, F17. The low acrylonitrile content of this compound provides excellent low temperature flexibility, in sealing conditions where resistance to mineral oil, alcohol, paraffin and low-aromatic petrol is required. Not recommended for use with acetone, benzene, chlorinated solvents or high-aromatic petrol. Good water resistance but poor against ozone and weather.&&
