RUBBER SPONGE

Closed Cell Sponge Rubber Gaskets

Commercial Gasket & Packing is a leading manufacturer of high quality open and closed cell sponge rubber gaskets and seals. Most grades are available in soft, medium and firm densities, and each offers a unique set of physical properties. The standard thicknesses of closed cell sponge range from 1/32″ up to 2″ thick. The majority of closed cell neoprene sponge rubber and blended sponge rubber products meet UL94HF-1 flame rating. Our most common commercial closed cell neoprene blend sponge styles: SCE41, SCE42, SCE43, and SCE45. Closed cell sponge rubber gaskets are available with or without pressure sensitive adhesive (PSA) backing. Closed cell sponge rubber gaskets are utilized in a variety of industries including: appliance, automotive, construction, sports equipment, electrical enclosures, HVAC, marine, and lighting.

Commercial Gasket & Packing maintains a full line of closed cell sponge rubber gasket materials. The materials most frequently used include:

Closed Cell Neoprene Sponge Rubber (100% Neoprene Sponge) Resists light oil contact, ozone, alkalis and acids, a good choice for general enclosure door gaskets. It is serviceable from -40°F to 158°F continuous and intermittent temperatures up to 200°F. Meets UL94HF-1 flame rating.
Closed Cell Blended Sponge Rubber (Neoprene/EPDM/SBR Blend) Most often used for general purpose sponge gaskets. Meets UL94HF-1 and will take -70°F without cracking due to superior cold resistance.
Closed Cell EPDM Sponge Rubber Closed cell EPDM sponge is used most often with outdoor conditions such as water, ozone and indirect sunlight. These materials do not meet the UL flame rating do not withstand oils or fuels.
Closed Cell Nitrile (Buna-N) Sponge Rubber Nitrile closed cell sponge rubber is an excellent gasket material for sealing applications that require oil and UV resistance. Also resistant to vegetable oil, animal oil, and mineral oil, gasoline, diesel and other aliphatic and aromatic hydrocarbons. Closed Cell Nitrile (Buna-N) Sponge Rubber can handle temperatures ranging from -40°F to +200°F.
Closed Cell Viton® Sponge Rubber Closed Cell Viton® Sponge Rubber is a sponge formulation that is manufactured with a continuous skin on both sides. The skin makes the sponge stronger and more tear resistant. Even when the skin is punctured or cut, the sheets will not allow passage of air or fluid between cells. These gaskets are highly compressible, resilient, light weight and provide good thermal insulation. It is generally resistant to aliphatic and aromatic hydrocarbons, oils, acids, hot water, fuels, ozone, lubricants and animal or vegetable oils. Closed Cell Viton® Sponge Rubber can handle temperatures ranging from -10°F to 400°F.New Paragraph

Silicone Sponge Gaskets

Commercial Gasket & Packing is a manufacturer of high quality silicone sponge gaskets, seals and custom silicone sponge products. These materials range from commercial to aerospace grade. They are mainly used for thermal shielding, vibration mounts, press relief pads, environmental cushioning and gaskets. These materials excel in any application requiring UV, ozone and weather resistance. Silicone sponge has a high tensile and tear resistance making it more durable than silicone foam. It is available in four grades; soft (5-9 psi), medium (6-14 psi), firm (12-20 psi) and extra firm (18-24 psi). This material is flexible and compressible, has thermal stability, non-stick properties and has ozone and UV resistance. It is available in many different formulations to give it low compression set, flame resistance, thermal conductivity, and fuel resistance. Silicone sponge is also available with fabric reinforcement to give it stability. Silicone sponge is available from 1/2″ to 2″ thick and can handle extreme temperatures ranging from -100°F to + 500°F. Pressure sensitive adhesive (PSA) backing is available in standard or acrylic to offer excellent adhesion properties.

Closed Cell Sponge Weather Stripping

Commercial Gasket & Packing manufactures closed cell sponge weather stripping in convenient roll lengths. We supply four different density options: soft, medium, medium/firm, and firm. Commercial Gasket & Packing offers our weather stripping in thicknesses ranging from 1/32″ through 1″ thick in widths from 1/8″ to 6″ wide. Rolls are available with or without pressure sensitive adhesive (PSA) backing (with peel-off liner).

Open Cell Sponge Rubber Gaskets

Commercial Gasket & Packing produces precision die cut, open cell sponge gaskets from a variety of, thicknesses, hardness, and grades. The standard thickness of open cell sponge rubber typically ranges from 1/16″ up to 1″ thick. Open cell sponge rubber gaskets are available with or without pressure sensitive adhesive (PSA) backing.

Commercial Gasket & Packing maintains a full line of open cell sponge rubber gasket materials. The materials we most frequently use include:

Natural Open Cell Sponge Natural open cell sponge is excellent for cushioning applications as well as applications that requires a skid resistant surface. This material does not take a compression set. It is available in soft, medium, medium/firm, firm, and extra firm grades. Natural Open Cell Sponge can handle temperature range from -40°F to 160°F.
Neoprene Open Cell Sponge Neoprene Rubber open cell sponge has all the same features of the natural open cell sponge and also works well in applications that come in contact with petroleum-based products. This material also meets various military and ASTM specifications including Mil-R-6130, Mil-C-3133, and Mil STD 670 and is available in soft, medium, and medium/firm grades.
