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.
We can supply material: Silicone, NBR, EPDM, FKM&FKM, NR, HNBR, SBR, Neoprene, PU,
FFKM, etc . You can choose material as your requirements :
|
