Silicone Sponge

Open Cell Sponge

Closed Cell Sponge

*Silicone Sponge is excellent for gasketing and padding that require a soft, compressible material.

*The closed and partially-open cells of these sponges prevent water absorption, in addition to ozone, weather and UV resistance typical of silicone.

*Open Cell Sponges are composed of connected cells that allow air or gas to pass through when compressed.

*These sponges offer good compression set characteristics and typically rebound faster than closed cell sponges.

*Closed Cell Sponges are neoprene/EPDM polymers that are excellent for applications requiring a soft, compressible material.

*Being extremely impermeable to water make them an excellent choice for shock absorption, weather sealing and thermal barriers.
