About HNBR
HNBR has been developed to meet higher temperatures than the standard NBR, while being resistant to petroleum-based oils. Obtained by hydrogenating the nitrile copolymer, HNBR fills the space left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength, while maintaining the excellent resistance to engine oils, sour gas, amine/oil mixtures, oxidized fuels and lubricating oils.
HNBR applications
HNBR is resistant to mineral oil-based hydraulic fluids, animal and vegetable fats, diesel fuel, ozone, acid gas, dilute acids and bases. HNBR is also resistant to new bio-oils (organic oils). HNBR is suitable for high dynamic loads and has good wear resistance. HNBR is suitable for temperatures from -30°C to + 150°C (-20°F to + 302°F).
The carboxyl group is added to significantly improve the wear resistance of NBR while maintaining excellent oil and solvent resistance. XNBR compounds offer high tensile strength and good physical properties at high temperatures. XNBR is suitable for temperatures from -30°C to + 150°C (-20°F to + 302°F).
