Nitrile (HNBR) / 氫化丁腈橡膠
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.
For HNBR the Service Temperature is from -40 C to 150
C and some special compounds can handle up to 160
55 to 90 Shore A are available.
Black, green, blue, brown, rust and gray are available,
or any Color we can design for
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
