Hydrogenated nitrile rubber sealing ring , because of its good performance, is widely used in the air conditioning industry. It has better abrasion resistance, tear resistance and compression resistance than nitrile rubber.

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 because of 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 resistance to compression and permanent deformation; at the same time, hydrogenated nitrile rubber also has high strength, high tear properties, excellent wear resistance, etc. It is one of the rubbers with excellent overall performance.


Advantages of hydrogenated nitrile rubber seals: better abrasion resistance than nitrile rubber, excellent resistance to corrosion, tensile, tear and compression, and good resistance to atmospheric conditions such as ozone, Generally suitable for washing or dishwashing detergents.

Disadvantages of hydrogenated nitrile rubber seals: Not recommended for use in alcohols, esters or aromatic solutions.
