Description
EPDM Foam(Closed Cell): 110-150kgs/m3
EPDM Foam(Open Cell): 95-100kgs/m3
General Characteristics of EPDM Sponge Sheet:
1. Closed cell structure making it impermeable to air and water and therefore an ideal material for sealing against air and/or water.
2. Outstanding aging properties and will not go brittle over time.
3. Very durable and relatively cheap.
4. Available in a wide range - high temperature, hard, soft, supersoft.
5. Good UV resistance.
6. Good mechanical properties.
7. Wide temperature range.
EPDM sponge sheet has superb air tight and water tight properties. Our EPDM foam sheeting is generally used within the automotive, electronic and construction trades. It is also a very good material for jointing expansion, weather strips, glazing seals and closure seals as well as being used for shock and noise absorbers and deadening. Its properties also make it suitable for requirements including thermal insulation on items such as garage door seals.
