Silicone Foam Gaskets

Foam silicone gasket products are closely related to silicone sponge gaskets. However, they typically use platinum cure liquid silicone, and are cast onto a smooth liner giving them a smooth skin. Silicone foam products can range in cell structure from very open cell to mostly closed cell. The open cell silicone products can be used for dust seals or shockvibration gaskets. The mostly closed celled silicone foam can be used for environmental seals. Gaskets made from silicone foam would be considered to be both high temperature gaskets and low temperature gaskets due to silicone's mechanical stability in temperature extremes. Silicone is also very stable by nature under UV. BISCO® silicone foams are certified by Underwriter Laboratories (UL) to have a flame rating of UL 94V-0 making them an excellent choice for electrical enclosure gaskets.
