Following are technical specifications for SG's Commercial Neoprene Blend Sponge and EVA Foam or Sponge.  These materials are available in sheets, stripping, or die cut configurations in thicknesses ranging from 1/16" up.  Pressure Sensitive Adhesive (PSA) with protective liner backing is available on both.

Both materials are excellent for general sealing purposes, especially where resistance to moisture absorption might be important and irregular surfaces are involved.  Of the two, Neoprene is slightly higher in cost and is generally more durable and suitable for higher temperature applications.  On the other hand, EVA is slightly more resilient, as shown by the Compression Deflection and Elongation figures below.

Standard Gasket has many other varieties of cellular sponge and foam products which will be added to this web site in the future.   These include Silicone Sponge for higher temperature applications, PVC Foam for UV resistance and resilience, Polyurethane foam, etc.  Whatever your Sponge or Foam Rubber application requirements are, SG can help you find the best and most cost effective solution.
