Nitrile Closed Cell Sponge Rubber

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 +250°F. Atlantic Gasket Corporation located in Philadelphia is a leading custom gasket and seal manufacturer, offering a wide variety of sponge materials, including three grades of Nitrile (Buna-N) closed cell sponge rubber: soft density C41NBR, medium density C42NBR and firm density C43NBR. These three grades are a pure Nitrile - not a blend, which offers enhanced oil resistance.

Example Gasket Application Properties
Fuel (gasoline and diesel) Style C41NBR, C42NBR and C43NBR closed cell Nitrile sponge is a pure Nitrile and is an excellent gasket material for sealing petroleum-based fuels such as gasoline, diesel and other aliphatic and aromatic hydrocarbons.
Non-fuel Nitrile closed cell sponge works exceptionally well as a gasket material in applications that will be exposed to animal oil, vegetable oil, mineral oil and lubricating oil.

Is Nitrile rubber the material of choice for your gasket or sealing application? Find out by reading on.
  • Does your application require a soft conformable gasket material that will seal petroleum-based products? Will your sealing gasket require UV resistance? Do you require a gasket material that will perform well in temperatures as low as –40° F and as high as +250° F? If you answer yes to any of the above questions, our style C41NBR, C42NBR and C43NBR closed cell Nitrile sponge may be the right material for your application.
  • Would it make your assembly process easier if your gasket was supplied with an adhesive backing? Atlantic Gasket has many standard stocked adhesives and would gladly recommend the best adhesive based on your specific sealing application.

Generally, Nitrile closed cell sponge rubber is the ideal gasket material for sealing petroleum-based products in applications that require a conformable gasket material. Our Nitrile closed cell sponge rubber gasket material meets various specifications, including:

  • ASTM-D-1056-67 SBE41, SBE42 and SBE43
  • ASTM-D-1056-07 2B1, 2B2 and 2B3
  • ASTM-D-1056 F1, M
  • FMVSS-302

To maintain a leading custom gasket and seal manufacturer position, Atlantic Gasket offers Buna-N closed cell sponge rubber as thin as 1/16" thick and as thick as 1-1/2" in sheets 40" wide x 68" long. Better yet, allow us to use our eighty plus years of die-cutting experience to produce a die-cut or waterjet cut part to your exact specifications. Not sure of the best material for your application? No problem. Please contact Atlantic Gasket and one of our experienced sales engineers will be glad to assist you in determining the right material for your gasket or sealing application.
