Hydrogenated Nitrile (HNBR) / 氫化丁腈橡膠

Hydrogenated Nitrile is a synthetic polymer that is obtained by saturating the hydrocarbon chains of Nitrile rubber with hydrogen. This special hydrogenation process reduces lots of double bonds in the main chain of the NBR polymer, so HNBR possess superior heat, ozone, chemical resistance and mechanical characteristics over standard Nitriles.
.
Service
Temperature
For HNBR the Service Temperature is from -40 C to 150 C and some special compounds can handle up to
160 C.

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 the auto and oil industries. For environment requirements 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 systems HFC134a (R134a) and PAG lube, because CR will degrade PAG lube and FKM will swell more in R134a, The available rubber is HNBR for these Applications.

産品特性:
