HNBR Rubber Features:

Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly SaturatedNitrile

(HSN), is special class of nitrile rubber (NBR) that has been hydrogenated to increase

saturation of the butadiene segment of the carbon polymer backbone. Subsequent

improvements to the material properties, over that of a nitrile rubber (NBR), include

greater thermal stability, broader chemical resistance, and greater tensile strength.

HNBR is classified by ASTM as a DH-type polymer. This classification indicates 150ºC

service temperature as well as less than 30% swell in IRM 903 oil. HNBR can be formulated

to meet application temperatures ranging between -50°C and 165ºC.
