EPDM Closed Cell Foam

EPDM Closed Cell foam
Fostek Corporation defines its EPDM closed cell family as foams, when tested to ASTM D1056 @ 25% compression deflection, results in a range of 13.8 kPa up to 89.6 kPa max. The corresponding psi (pounds per square inch) products are in the 2-5 psi; 5-9 psi; 9-13 psi; and 12-16 psi ranges.Fostek’s point of difference encompasses choices of compression deflections to target specific applications and needs for our customers. Fostek can “tune in” its foams for new engineering and design challenges to deliver the desired performance.
What is EPDM Closed Cell Foam used for?
Closed-cell foams are utilized in many of the same applications as our semi-closed foams. Fostek’s EPDM closed cell foam delivers excellent performance and durability for a variety of applications. Our proprietary “family” of EPDM foam products are used in the automotive industry as well as in appliance, weather stripping, and general industrial uses for a variety of applications and can be either die cut or in custom profile form, often with PSA.- NVH (noise, vibration, & harshness) seals, gaskets, pads, closure strips, pillar stuffers, cushioning in or around windshields, door panels, instrument panels, headliners, etc.
- Acoustic / sound control in or around windshields, door panels, instrument panels, headliners, etc. These are used alone or in composite to achieve STL (sound transmission loss) targets in a vehicle component “system”…i.e. a door “system” that includes the metal door, the glass, and the inner cabin door trim panel.
- HVAC seals and gaskets providing air and water sealing
- APPLIANCES utilize these foams for the same performance reasons as listed above
- Applications that need very good UV resistance and a wide operating temperature are excellent applications for our EPDM foams: weather stripping; construction seals; window glazing seals, etc. These are used in custom profile form as well as die cut and stripping.
More information about Fostek EPDM Closed Cell Foam
Fostek’s continuous roll technology produces EPDM closed cell foam rolls that range in gauge from 3mm thick to 32+ mm thick. We believe we have capability up to 38+mm, Fostek’s closed cell technology produces a consistent cell structure. Rolls are available in a variety of widths and lengths. The most common widths are a roll of a minimum width of 54 inches and a roll with a minimum width of 27 inches. Black is the most common color, however, we have also produced EPDM foam in a natural color. Other colors may be available based on minimum volume requirements. Depending on certain parameters, closed cell foams are available with skin-two-sides, skin-one-side, and no skin. The most common packaging for these products to adequately protect them during shipping and handling is to place them in boxes on skids.For more information on Fostek’s EPDM closed cell foam, please contact our sales office at 574-284-1000 or click here to contact us and receive a prompt reply.
