EPDM Sponge Rubber is a closed cell sponge rubber product which makes it ideal for sealing applications.

The real name for this is Ethylene Propylene Diene Monomer. Used where oil resistance isn’t a requirement and in many general gasket/seal outdoor applications due to excellent ozone, UV light resistance, weatherability.

Neoprene / EPDM Blends

These are copolymers of Neoprene and EPDM closed cell sponge rubbers, which offer the properties of both grades of materials. The blend ratio’s dictate the properties to a certain extent. Such foams are becoming increasingly the predominant grades, replacing both pure Neoprene and EPDM as a good General Purpose grade of sponge rubber.

Used where low resistance to oil and UV/Ozone is necessary but a degree of fuel and oil resistance.

Flame Retardant classification to UL94 HF 1 is available. The foams can be supplied with or without a self adhesive backing and can be cut into coils for sealing tapes.
