SYNTHETIC NITRILE RUBBER PNBR/NBR

Product description
Synthetic nitrile rubber is an acrylonitrile and butadiene-1.3 copolymer obtained by emulsion polymerisation. Product form – briquettes of (30±1) kg. Synthetic nitrile rubber (27–30% acrylonitrile content) filled with polyvinyl chloride (PVC) is obtained by coagulating nitrile latex with polyvinyl chloride latex. All nitrile butadiene rubbers contain a non-staining antioxidant.
