Foam Gasket

Foams (or sponges) are soft by nature and generally specified for simple sealing applications. They are more flexible and malleable than solid rubbers of the same material. Open cell foams have cells, or air spaces, which are interconnected and will thus allow the passage of liquids or gases.Open cell foam gaskets are primarily used for shock or vibration applications. Closed cell foam gaskets are used primarily for environmental seals where the material would be exposed to challenging outdoor conditions, such as sunlight, dust, cold and moisture.
