EPDM Foam

EPDM foam is a cellular elastomeric material produced from Ethylene Propylene Diene Monomer rubber. It undergoes specialized compounding and expansion processes to create either a closed-cell or open-cell structure known for exceptional weather resistance and flexibility.

Closed-cell EPDM foam has non-porous, sealed cells that prevent air and moisture penetration, making it ideal for waterproof seals. Open-cell EPDM foam features interconnected pores that offer superior compressibility, flexibility, and sound absorption.

EPDM foam sheets feature a cellular, compressible structure ideal for lightweight cushioning, thermal insulation, and flexible gasketing. In contrast, EPDM rubber sheets are solid or semi-solid elastomers designed for heavy-duty industrial linings, high-load vibration pads, and robust mechanical seals.

EPDM density determines the foam’s weight, compression deflection, and load-bearing capacity. Higher-density variants offer greater tensile strength and structural rigidity, whereas lower-density options provide softer cushioning and easier compressibility for sealing gaps.

Yes. Closed-cell EPDM is globally recognized for its superior resistance to ozone, UV radiation, sunlight, and extreme weather fluctuations, making it one of the most reliable polymers for permanent outdoor use without cracking or degradation.

EPDM tape—typically equipped with a high-strength pressure-sensitive adhesive backing—is widely used in construction, automotive assembly, and HVAC systems for rapid weatherstripping, gap sealing, draft prevention, and acoustic dampening.

Fusion Foams supplies directly to global businesses, commercial buyers, and industrial partners through our international distribution network. Contact our commercial team to connect with authorized suppliers near your location.

Yes. As an established manufacturer, we provide precision cutting, splitting, and sizing options for EPDM foam sheets and rolls to suit exact industrial specifications and commercial project requirements.

EPDM maintains its flexible elastomeric properties across a broad temperature spectrum, resisting hardening in freezing sub-zero environments and preventing thermal breakdown under high heat exposure.
