Silicone foam is manufactured from a low viscosity liquid silicone which is cast on a smooth liner and cured through inline
ovens. Silicone foam can be supplied as an open cell, closed cell or combination of both, open and closed cell material.
Silicone sponge, on the other hand, is mixed and calendered on a rubber mill then cured via inline ovens or stationary mold
press.
Silicone foam is typically lighter in density, compresses with less force and has a lower compression
set than silicone sponge. Both products have good sealing properties, however the sponge has higher tensile strength and the foam has better flame
resistance. All materials can be supplied with high temp acrylic adhesive or in custom die cut configurations.
