Buna-N is a general-purpose oil resistant polymer known as Nitrile Rubber. It is a copolymer of butadiene and acrylonitrile. Buna-N has good resistance to solvents, oil, water, and hydraulic fluid. It displays good compression set, abrasion resistance, and tensile strength. Buna-N should not be used in highly polar solvents such as acetone and methyl ethyl ketone, nor should it be used in chlorinated hydrocarbons, ozone, or nitro hydrocarbons. In most cases it is interchangeable with Neoprene.
