Open cell silicone foam is white in color, lightweight and flexible with a smooth skin on both sides. Its unique characteristics and chemical makeup allow this material to conform to its original state after being compressed. Open cell foam is soft, breathable, and flexible which enables it to create a conformable seal required by sealing applications. The only limitation of open cell foam is that it is not as durable as closed cell foam.
Silicone foam can be used for insulating and cushioning electronic assemblies. It can also be used for gaskets, seals, air filters, thermal shielding, cushioning for aviation, automotive and locomotive industries as well as flame-retardant applications. Silicone foam is also approved for repeated food contact per 21 CFR 177.2600
Closed cell silicone foam offers a compression deflection of a medium density sponge but has the light density of open cell foam.
