HNBR has a reasonable molecular structure. It not only inherits the oil resistance and wear resistance of NBR but also has better heat resistance (up to 165℃), oxidation resistance, ozone resistance, and chemical resistance. It is comparable to FKM and can replace FKM, CR/ NBR, and other special elastomers in many aspects. It is used in the automotive, electronics, home appliances, petrochemicals, smart wear, wires and cables, and other industries.
