Sponge Rubber

The Norseal® full line of closed cell expanded silicone sponge rubber for a variety of gasketing, cushioning, insulating and protective applications, over a wide temperature and environmental range. Our experts can help you chose the proper product for your requirements, including formulations designed for general gasketing, flame retardant cushions, specification grade, solvent resistant gaskets and weather seals.

Key benefits of our closed cell sponge include thermal stability over a wide temperature range, excellent compression set resistance, ozone and UV resistance. Saint-Gobain subjects all of our closed cell sponge products to a special final cleaning process that lowers the material out gassing for cleaner operation.
