What is HNBR?
“HNBR” stands for Hydrogenated Nitrile Butadiene Rubber, which is a specialized type of synthetic rubber known for its enhanced heat, oil, and chemical resistance compared to standard Nitrile Butadiene Rubber (NBR). HNBR is created through the hydrogenation of NBR, resulting in a material with improved properties for demanding applications. Such as automotive, oil and gas, industrial manufacturing, and more, where resistance to heat, oil, and chemicals is critical.
