Hydrogenated Butadiene Rubber (HNBR) Hydrogenated Butadiene Rubber (HNBR) A copolymer of butadiene and acrylonitrile.
It is obtained by fully or partially hydrogenating the double bonds in the butadiene of NBR. It is characterized by high mechanical strength and abrasion resistance, better heat resistance than NBR when crosslinked with peroxide, and other properties the same as nitrile rubber. The disadvantage is that the price is higher. Operating temperature range: about -30℃~+150℃. Mainly used for oil-resistant, high-temperature-resistant sealing products.
