Difference Between NBR and HNBR
The key difference between NBR and HNBR is that NBR is a non-hydrogenated form, whereas HNBR is a hydrogenated form.
NBR is the shortened form of nitrile rubber. HNBR is the hydrogenated form of nitrile rubber. It is a synthetic copolymer of acrylonitrile and butadiene. HNBR or hydrogenated nitrile rubber is widely used due to its physical strength and retention of properties even after the exposure to heat, oil, and chemicals.
