NITRILE NBR RUBBER - In addition to its resistance to petroleum oils and aromatic hydrocarbons, NBR is highly resistant to mineral oils, vegetable oils, and many acids. It also has good elongation properties as well as adequate resilience, tensile and compression set.
Because of its cost, this elastomer is not usually recommended for applications where oil resistance is not a major problem. Where oil resistance is required, the cost is more than justifiable. NITRILE RUBBER is generally attacked by ozone, ketones, esters, aldehydes, chlorinated and nitro hydrocarbons.
Nitrile Rubber Chemical Designation: Butadiene Acrylonitrile (NBR)
