Sponge silicone gaskets have a cellular structure that offers cushioning and padding. There are two basic types of sponge silicones: open-cell and closed-cell. Open-cell silicones contain interconnected pockets that allow water, air, and chemicals to pass unless the gasket is compressed. Closed-cell silicones have pockets that are filled with nitrogen to prevent these substances from passing at low pressures.
