HNBR diaphragm

Hydrogenated acrylonitrile butadiene rubber (HNBR) can be produced from conventional nitrile rubber by hydrogenation of the unsaturated bonds in the butadiene units of the polymer. The properties of HNBR diaphragm depend upon the acrylonitrile content and the degree of hydrogenation of the butadiene copolymer. HNBRs have better oil and chemical resistance than nitrile rubbers and can also withstand much higher temperatures.
