Open & Closed CellsSeal & Design specializes in fabrication of silicone sponge material.

Most commercially available silicone sponge products are made from gum based polydimethylsiloxane (PMDS). The silicone elastomer is expanded at the time it is heat cured; the expansion process creates the closed cell sponge structure. The main difference between a "sponge" and a "foam" is that a sponge is closed cell while a foam is open cell.

Advantages of silicone sponge are a wide operating temperature, good water sealing properties, compression set resistance, and UV and ozone resistance. Silicone sponge rugged and is a good choice for applications in outdoor environments.

Seal & Design fabricates silicone sponges to meet customer specs. We can also provide the silicone sponge products with adhesive backings for easy end application. Check out our silicone sponge offerings below.
