olded Parts Aerospace Vip Rubber and Plastic NitrileWith great petroleum resistance and excellent custom compounding options, Nitrile NBR, Buna-N™ is a popular material choice. copolymer of butadiene and acrylonitrile, Nitrile has excellent resistance to silicone greases, hydraulic fluids, alcohols, and water. It also has a favorable balance of good compression set, high abrasion resistance, and high tensile strengths. And in many industries requiring good performance in low temperatures Nitrile also performs very well.

Nitrile is ideal for any use where the rubber will contact oiled surface or be exposed to oil or fuel. In engine systems, it can be used to produce parts such as gaskets, seals, hydraulic hoses, carburetor and fuel pump diaphragms and O-rings. It is also used for rubber-to-metal bonded components, molded shapes, rubber bumpers or for contact with oily surfaces.

Nitrile rubber can be extruded, molded and made into rubber sheet.


Nitrile is ASTM 2000 Classification: BF, BG, BK and is known by its chemical definition as Butadiene Acrylonitrile.

Nitrile is used within the automotive industry for engine systems including fuel systems and gaskets requiring exposure to oil. It is also extensively used with the Oil and Gas industry for seals, tubing molded shapes and is especially popular within the Military industry for use in fuel systems, engine housings and in any mechanical, flight or marine environment where exposure to oil is required.
