Material Data Sheet HN112-B85
H-NBR HN112-black (Peroxide cross linked)

General

HN112-B85 is a black hydrogenated acrylnitrile-butadiene- rubber commonly referred to as H-NBR. Good physical characteristics and chemical resistance to the most common hydraulic fluids makes it an excellent sealing material. H-NBR materials are often used in vegetable and animal oils as well as in high addivated oils, sour oils/gases( H2S)and crude oil
