What is a closed cell foam sheet?

Closed cell foam sheetsClosed cell sponge, or closed cell foam sheet, is ideal for sealing against air or fluid in specific applications. Closed cell foam rubber materials are most commonly produced from polyethylene foam and provide a strong, chemical resistant material, suitable for use within a range of settings, from insulation and general use through to more demanding industrial applications. Its resistance to chemicals and grease means that this particular foam rubber sheet can also be used in manufacturing and automotive industries for shock absorbing purposes. Due to the rigid properties of closed cell foam sheets, it isn’t susceptible to wear and tear, meaning it fares well in such demanding applications such as industrial environments. Closed cell foam sheeting is stocked in a range of thicknesses, densities and materials, with special grades available to also allow properties such as shock absorption and acoustic or thermal insulation.

Rubber foam sheets are available to purchase from Martins Rubber in a range of thicknesses. We also provide the option of buying foam rubber cut to size to suit your individual application or particular project. For more information, please speak to one of our technical specialists.
