EPDM Closed Cell Foam
Fostek Corporation manufactures high quality plastic and rubber blended, closed and semi-closed cell foams in our continuous roll process as well as in custom profile shapes. Fostek has developed and produces our family of EPDM closed and semi-closed cell foams in our IATF 16949:2018 certified production facility in Bedford, Virginia.
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.
NOTE: In some systems, Fostek’s EPDM foam with skin 2 sides might be used at 5mm (+/-) as a functional acoustic/moisture control material.
