CR Rubber Orings Hydrogenated Nitrile Rubber HNBR Orings
PROPERTIESHydrogenated acrylonitrile butadiene rubber (HNBR) is a unique elastomer. It can be produced from conventional nitrile rubber by hydrogenation of the unsaturated bonds in the butadiene units of the polymer:
The properties of hydrogenated nitrile rubber (HNBR) 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. Like NBR, this type of elastomer has excellent resistance to oils and fuels but it also has excellent resistance to many chemicals, heat (steam / hot water) and ozone. The mechanical properties like tensile and tear strength, elongation, and abrasion resistance are also excellent. Furthermore, HNBRs have good dynamic behavior at elevated temperatures.
Cure System, Peroxide-Cured:
HNBRs are usually peroxide-cured but can also be sulfur-cured to improve flexible properties in dynamic systems. However, sulfur-curing will reduce the heat resistance and cause an inferior compression set.
