Nitrile (also known as Buna-N) closed cell sponge rubber is an excellent gasket material for sealing applications that require oil and UV resistance. With a high resistance to vegetable oil, animal oil, and mineral oil, Buna-N also performs well as a gasket or sealing material in petroleum-based applications. Also, Nitrile rubber gasket material is able to maintain its properties in commercial or industrial applications where temperatures range from -40°F to +200°F. Atlantic Gasket Corporation located in Philadelphia is a leading custom gasket and seal manufacturer, offering a wide variety of sponge materials, including two grades of Nitrile (Buna-N) closed cell sponge rubber: soft density SBE41NIT; and medium density SBE42NIT. These two grades are a pure Nitrile - not a blend, which offers enhanced oil resistance.
