Nitrile rubber possesses unique physical and chemical properties that make it one of the most widely used synthetic elastomers in the world. It is meant for use in pads, seals, and general gasket applications. Also known as Buna-N rubber or butadiene rubber, it has a superior level of resistance against synthetic and natural grease product. It is highly recommended for use in areas where oil/petroleum products are present. This material was developed during World War II in response to a growing need for oil-resistant rubber that could serve as a superior alternative to Natural rubber. Nitrile rubber proved to be a great solution.
