HNBR rubber ring

Material: Hydrogenated Nitrile Rubber (HNBR)

Color: black, green

Hardness: 40~90 degrees

Special rubber ring for car air conditioner

Performance: Hydrogenated nitrile rubber (HNBR) is a highly saturated elastomer obtained by special hydrogenation of nitrile rubber. Hydrogenated nitrile rubber has good oil resistance (good resistance to fuel oil, lubricating oil, and aromatic solvents); and due to its highly saturated structure, it has good heat resistance and excellent chemical resistance (to Freon, acid and alkali have good resistance), excellent ozone resistance, high compression and permanent deformation resistance; at the same time hydrogenated nitrile rubber also has high strength, high tear performance, excellent wear resistance, etc. It is one of the rubbers with excellent comprehensive performance.

The high temperature resistance of HNBR is 130～180℃, and the cold resistance is -55～-38℃. It is resistant to freon, and is used in professional auto parts, air conditioners, and has strong low temperature resistance.
