Foam Materials
In addition to the wide range of sponge materials, Atlantic Gasket has many foam materials available that are diverse in their chemical composition and mechanical properties. Some of the most common types used for gaskets and other die cut parts are:
Crushed cellular foam, or semi-closed cell, is very soft (less than 1 psi on the 25% Compression Deflection scale) and is designed for sealing flexible or uneven substrates. This material is a closed cell foam that is crushed to create small ruptures in the cells, allowing greater compression and less compression set than closed cell foams. Atlantic Gasket offers crushed cellular foam in both EPDM (Ensolite EFO) and PVC Nitrile (Ensolite SFO) versions. Both grades meet many automotive specifications for environmental exposure and temperature. Click here for material specifications and additional information on Crushed cellular foam.
