Uncompromising Performance

Our commercial-grade EPDM closed cell sponge rubber sheet represents the pinnacle of synthetic rubber engineering. Manufactured to exacting standards, this material delivers exceptional resistance to water, salt water, weathering, UV radiation, and ozone degradation—making it the material of choice for marine, automotive, and industrial sealing applications.

The closed cell structure provides superior compression set resistance and water impermeability, whilst maintaining excellent flexibility across a wide temperature spectrum. Unlike open cell alternatives, moisture cannot penetrate the cell walls, ensuring consistent performance in wet environments.

Key Performance Characteristics

Water & Salt Water Resistant — Impervious to fresh and marine environments
Weatherproof Construction — Withstands prolonged outdoor exposure without degradation
UV & Ozone Resistant — Maintains integrity under direct sunlight and atmospheric ozone
Closed Cell Technology — Zero water absorption, superior compression recovery
Temperature Stable — Performs reliably from -40°C to +120°C
Excellent Compression Set — Retains sealing force over extended service life

Applications & Industries

Marine & Offshore

Hatch seals, porthole gaskets, deck fittings, hull penetrations

Automotive & Transport

Door seals, window gaskets, vibration damping, weatherstripping

HVAC & Building Services

Duct sealing, thermal insulation, acoustic damping, expansion joints

Industrial Manufacturing

Equipment gaskets, protective padding, vibration isolation, sealing strips

Why Specify EPDM Closed Cell?

EPDM (Ethylene Propylene Diene Monomer) offers superior weather resistance compared to natural rubber, neoprene, or nitrile alternatives. The closed cell structure prevents water ingress, making it ideal for outdoor, marine, and wet environment applications where open cell foams would fail. Its exceptional ozone and UV resistance ensures decades of reliable service without hardening, cracking, or loss of elasticity.

Frequently Asked Questions

What rubber compounds are available?

We supply SBR (general purpose), EPDM (weatherproof, outdoor), nitrile (oil-resistant), neoprene (chemical-resistant) and natural rubber. Choose the compound based on your application requirements.

Can rubber sheet be cut to a custom size?

Yes — all rubber sheet is available cut to your exact size. Specify your dimensions at checkout or contact us for a bespoke cut.

What thickness do I need?

For light-duty surface protection, 2–3mm is sufficient. Workshop and industrial applications typically use 4–6mm. Heavy machinery bases and anti-vibration applications use 10–25mm.

Is the rubber sheet RoHS/food-safe compliant?

Compliance varies by compound. EPDM and silicone grades are available in food-safe specifications. Contact us with your compliance requirements.

What is the maximum sheet size available?

Standard roll widths are 1m and 1.4m. Lengths vary by compound and thickness. Contact us for oversized requirements or full roll pricing.
