HNBR (Hydrogenated Nitrile Butadiene Rubber) is obtained by fully or partially hydrogenating the double bonds in nitrile butadiene rubber with hydrogen into single bonds. Compared to NBR, HNBR has better properties in terms of oil resistance, temperature resistance and strength. It is more resistant to ozone and aggressive substances and can be used from -40 ° C to 165 ° C (with peaks up to 190 ° C). HNBR was developed in the 1970s by, among others, Shell [3] and Bayer (now Lanxess) [4]; Bayer / Lanxess' brand name is Therban. Another brand name was Tornac from Polysar, which was subsequently bought up by Bayer.
HNBR has been developed to meet higher temperatures than the standard NBR, while it is resistant to oil-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 excellent resistance to engine oils, acid gas, amine / oil blends, oxidized fuels and Hydronated nitrile rubber (Hydrogenated nitrile rubber HNBR)
Patented by Bayer in 1975 and the first to be marketed in 1986 under the name Therban.

HNBR is a saturated NBR version with a much higher temperature resistance. With ACN levels of 18-49% and a saturation degree of 80-99%. Temperature resistance possibilities from -45 degrees to +165 degrees and peaks up to `80 degrees.

You could say that HNBR fills the gap between NBR and FKM. HNBR is still resistant to aggressive media at higher temperatures.
lubricating oils remain.
Hydrogenated Nitrile Butadiene Rubber (HNBR) has been developed to bridge the price-performance gap between FKM / FVMQ and NBR. Compared with NBR, HNBR has better oil resistance, temperature properties and strength.

 

HNBR benefits:
• Resistant to mineral oil based hydraulic fluids
• Resistant to animal and vegetable fats

• Resistant to new organic oils (organic oils)
• Suitable for high dynamic loads and has good wear resistance
• Suitable for temperatures from -30 degrees C to +150 degrees C
• Mechanically strong
• Good compression set / good "hot tear" / good ozone and aging resistance
• Resistant to high energy radioactive radiation
• Good resistance to hot water and steam
• Temperature resistance to prolonged +150 degrees C with higher peaks
• Good resistance to various media
• Excellent heat and oxidation resistance
• Can be used in water and steam
• Temperature range from -30 degrees to +160 degrees C
• Excellent resistance to automotive fluids (engine oil, coolant, fuel etc.)

Cons HNBR:
• Considerably more expensive
• Not resistant to chlorinated hydrocarbons
• Not resistant to polar solvents (ketones, eaters and esters)
• Not resistant to strong acids
