What Is Open Cell EPDM Foam Sheet?

EPDM, or ethylene propylene diene monomer foam, is a versatile sponge rubber material used in many industrial and commercial applications. Open cell EPDM foam is softer and easier to compress than many dense foam materials, making it suitable for low-compression seals, cushioning pads, sound insulation and protective foam parts.

EPDM foam is valued for ageing resistance, durability, compressibility, thermal resistance, sunlight resistance, ozone resistance and weathering resistance. It performs well in outdoor and industrial environments where long service life is important.

Topsun open cell EPDM foam can be processed into sheets, rolls, strips, tapes with or without adhesive, blocks and custom gaskets. Thickness, density, size, color and adhesive backing can be customized according to the customer’s application.

Custom EPDM Foam Sheet, Roll, Strip and Gasket Options

Topsun can supply open cell EPDM foam in full rolls, sheets, strip cut lengths, die-cut gaskets and adhesive-backed foam tapes. The material can be used for soft sealing, cushioning, sound absorption, packaging protection and assembly applications.

Available customization options include thickness, density, width, length, sheet size, roll size, adhesive type, release liner, die-cut shape, laminated surface and packaging method. Customers can send drawings, samples or application details for material recommendation and quotation.
