Silicone Foam

This flexible, bobbly silicone foam sheet is probably used for some sort of industrial ironing application. Silicone is unaffected by prolonged exposure to temperatures of up to 200°C (392°F), and as a foam, would be a very effective heat barrier. The raised bobbles help support the ironing surface, while the perforations allow cool air and steam to circulate under the ironing mat.

This close-textured foam has a very fine bubble structure, formed in a liquid state as the silicone foam’s component ingredients react to produce hydrogen gas, which is trapped as the polymer solidifies. This is a self-skinning foam with a closed cell bubble structure, making it very robust, as well as water- and weatherproof. All silicone materials have excellent resistance to UV and chemical degradation, but are relatively expensive to produce.
