HNBR (Hydrogenated Nitrile Butadiene Rubber) is produced by hydrogenating NBR, which significantly improves heat resistance, ozone/weathering resistance, and mechanical strength compared to standard nitrile. HNBR O-rings are widely used in automotive powertrain, air conditioning systems, and oilfield applications where a higher-performance upgrade from NBR is needed without moving to a fluoroelastomer.
