As a leading gasket manufacturer, Atlantic Gasket utilizes a variety of foam and sponge materials to manufacture custom gaskets as small as .062” dia. and as large as 36” square as well as any size or shape in between. Gaskets can be supplied with internal cutouts including round holes, oval slots, square holes, etc. and any type of outside configuration imaginable. In addition, our foam and sponge gasket materials can be slit to your exact requirement and supplied in rolls. We welcome the opportunity to help you determine the optimal gasket design for your application at minimum cost.

Custom Foam and Sponge Gaskets Can Be Produced
from the Following Materials:

Closed Cell Sponge [Pure Polymers]

Neoprene offers good resistance to acid, alkali, gasoline, and oil. Neoprene can be supplied in 9 and 16# densities.

EPDM offers excellent ozone resistance and performs well in applications where temperatures can range from -90 to 275°F. EPDM can be supplied in 12 and 16# densities.

Nitrile offers excellent fuel resistance and excellent UV resistance and performs well in applications where temperatures can range from –40 to +200°F. Nitrile is supplied in 14# density.

ECH (Epichlorohydrin) offers excellent fuel resistance and performs well in applications where temperatures can range from –70 to +275°F. ECH is supplied in 15# density.

Silicone offers excellent sealing qualities, plus compression set, flame, ozone, and UV resistances. This high-end material is widely used for demanding applications and is excellent for applications that will be exposed to extreme temperatures ranging from –103 to 450°F. Our Silicone material is available from soft to extra firm densities in orange/red, black, gray, and white colors.

Closed Cell Sponge [Blends]

Neoprene/ EPDM/ SBR blend offers excellent resistance to acid, alkali, ozone, and oxidation. This blend can be supplied in 6 and 9# densities and performs well in applications where temperatures can range from –40 to +200°F.

PVC/ Nitrile blend offers excellent resistance to acid, gasoline, oil, and ozone. This blend can be supplied in 4, 5, 6, 7, and 13# densities and performs well in applications where temperatures can range from –40 to +160°F.

Neoprene/ PVC/ Nitrile blend offers good chemical resistance and is fire-rated. This blend can be supplied in 4, 6, and 8# densities and performs well in applications where temperatures can range from –40 to +200°F.

EVA (Ethylene Vinyl Acetate) offers excellent resistance to acid, alkali, ozone, and ketones. This blend can be supplied in 2, 4, and 8# densities and performs well in applications where temperatures can range from –70 to +160°F.

Open Cell Sponge

Natural Rubber open cell sponge is excellent for cushioning applications as well as applications that require a skid resistant surface. The major advantage of this material is that it does not take a compression set. This material is available in soft, medium, medium/firm, firm, and extra firm grades.

Neoprene Rubber open cell sponge has all the same features of the natural open cell sponge, but, in addition, it works well in applications that will 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.

Open Cell Foam

Polyurethane Foam is an UL94-recognized foam designed for dust seals, spacers, and cushioning applications. It is available in 2, 4, and 6# densities and in Polyether and Polyester formulations. Standard color is charcoal gray with special colors available upon request.

Closed Cell Foam

Cross-linked Polyethylene offers good mechanical properties, good thermal insulation, excellent chemical resistance, and low water absorption. Available in white and black, cross-linked polyethylene has a smooth skin and can be supplied in 2, 4, and 6# densities.

PVC Foam is conformable, UV resistant, and strong. PVC’s are widely used to seal out air, moisture, light, and dust. This foam is available in 6 to 15# densities in both black and gray colors and is relatively inexpensive.

Atlantic takes pride in being one of the pioneers in working with pressure sensitive adhesives. We currently stock Rubber-based, Acrylic-based, and Silicone-based Adhesives systems in both supported and unsupported constructions and can apply these adhesives to all the above materials.
