Silicone Foam and Sponge
Liqid based Silicone Foam, and gum based Silicone Sponge have combined properties of resilience, high temperature stability and general inertness unavailable in other foam or sponge sealing materials. They are generally unaffected by extended exposure to temperature extremes from -67°F (-55°C) to 392°F (200°C), and are also unaffected by aging and degradation from sunlight and ozone.
Silicone foam is typically lighter in density, compresses with less force and has a lower compression set than silicone sponge. Sponge has higher tensile strength and the foam has better flame resistance.
Silicones can withstand temperatures of 500 degree F. and above. Some of the products we make out of silicone include: Thermal Spray Masks, Paint Masks, Seals, Vibration Isolators & Dampeners, Valves, Gromets, as well as Molding to Metal, and Secondary Bonding to Metal & Other Composites.
Reinforced silicone combines rubber with layers of fiberglass or other material, woven in to increase the overall tear resistance and to decrease material strain.
Fluorosilicones are specified for applications requiring broad temperature range and resistance to fuels, coolants and oils.

We primarily compression mold or transfer mold silicone products from high consistency gum stock rubber. These materials can be formulated for high elongation, flex, tensile and tear properties, and can withstand temperatures from -100°F to 500°F. Gum based silicones are formulated to meet numerous aerospace specifications (see our TECHNICAL HUB.) We maintain inventories from 25 to 80 durometer Shore A and we provide special formulations upon request.
