SYNTHETIC NITRILE RUBBER PNBR/NBR

Product description

Nitrile-butadiene rubber (NBR) is an acrylonitrile and butadiene-1.3 copolymer obtained by emulsion polymerization method. Due to high resistance to aggressive agents NBR is widely used for manufacture of various oil-and-petrol resistant industrial rubber products. Product form – bales of 30±0,5 kg.
