Hydrogenated Nitrile (HNBR)
Hydrogenated Nitrile is a synthetic polymer that is obtained by saturating the hydrocarbon chains of Nitrile rubber with hydrogen. This special hydrogenation process reduce lots of double bonds in main chain of NBR polymer, so HNBR possess superior heat, ozone, chemical resistance and mechanical characteristics over standard Nitriles.
SERVIEC TEMPERATURE
For HNBR the service temperature is from -40℃ to 150℃ and some special compound can up to 160℃.
HARDNESS
55 to 90 Shore A are available.
COLOR
Black, green, blue, brown, rust and gray are available, or any color we can design for you.
APPLICATION
HNBR has wide applications in auto and oil industries. For environment requirement HCFC will be replaced by ozone-safe refrigerants-HFCs. 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. But CR and FKM is not adequate in the newer coolant system HFC134a (R134a) and PAG lube, because CR will degrade PAG lube and FKM will swell more in R134a, the available rubber is HNBR.
