Hydrogenated acrylonitrile-butadiene rubber( HNBR )
Properties:
Provided that the compounds are correctly formulated and processed, the vulcanizates have outstanding mechanical properties, very good resistance to abrasion, very good compression set behavior, excellent resistance to weathering, ozone and hot air and very good resistance to technical oils, even in the presence of hydrogen sulfide and amines.
Applications:
Heavily stressed rubber goods used in oil exploration and production, e.g. seal components, hoses, stators, and rubber goods for drill pipes. Also suitable for high quality gaskets, membranes, V-belts and timing belts for motor vehicles, cable sheathing, hydraulic hose and special couplings.
Food contact:
Information concerning FDA and BgVV approvals can be obtained on request from the Health, Safety, Environment and Quality Department (HSEQ) in the Business Planning and Administration Section of the Rubber Business Group |
