Hydrogenated nitrile (HNBR)seal ring HNBR O-rings HNBR Green O-Ring HNBR O-Rings & Seals Hydrogenated Nitrile Rubber (HNBR)
Hydrogenated Nitrile Rubber o-rings (Also known as HNBR or HSN o-rings ) is the product of hydrogenation of carbon-carbon double bonds on molecular chains of nitrile rubber, so it is also known as highly saturated 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, excellent chemical corrosion resistance (good resistance to freon, acid, alkali), excellent ozone resistance, high compression permanent deformation resistance; At the same time, hydrogenated nitrile butadiene rubber also has the characteristics of high strength, high tearing performance, excellent wear resistance, etc., is one of the most excellent comprehensive properties of rubber.
HNBR O-rings have wide application in the auto and oil industries. In old air conditioning and refrigeration equipment Chloroprene (CR) and Fluoroelastomer (FKM) are popular material with coolant system of HCFC (or CFC) and mineral oil.However neoprene O-rings and FKM O-rings are not adequate in the newer coolant systems HFC134a (R134a) and PAG lube, because neoprene will degrade PAG lube and FKM / Viton will swell more in R134a, The available rubber option in this case are HNBR O-rings which are ideal for the above application
