Neoprene/EPDM/SBR Closed Cell Sponge Rubber

The closed cell sponge rubber blend of Neoprene, EPDM, and SBR results in a gasket material suitable for diverse industrial and mechanical applications where durability, flexibility, and cost are essential. The combination of the best qualities of these three polymers creates an excellent material used in many diverse indoor and outdoor applications. Atlantic Gasket Corporation, a Philadelphia-based custom gasket manufacturer with an international presence, offers closed cell sponge rubber Neoprene/EPDM/SBR in 6, 9, and 12# densities. Listed below are just a few examples of suitable sealing applications for Neoprene/EPDM/SBR.

Example Gasket Application Properties
Weatherproofing Closed cell Neoprene/EPDM/SBR performs well in applications where temperatures can range from –40° F to +200° F. This gasket material is resistant to ozone, sunlight, and oxidation, and works well as a gasket in many outdoor applications.
HVAC The closed cell structure of Neoprene/EPDM/SBR closed cell sponge makes it an ideal gasket material to seal joints, panel doors, ducts, and other areas because of its ability to eliminate air leakage.
Automotive Closed cell structure is receptive to most pressure sensitive adhesives for bonding gaskets to metal and plastic surfaces for both sealing and cushioning applications.
Electrical Enclosures UL ratings make closed cell Neoprene/EPDM/SBR suitable for use in sealing equipment and enclosures containing electrical circuitry and components. This material meets UL157, UL50, UL508 and UL48, UL50E and UL94HF-1.
