What is Semi Closed Cell EPDM?

Semi closed cell EPDM foam is a flexible, weather-resistant material that offers a balance between compressibility and resilience.

With a slightly more open structure than fully closed cell variants, it adapts well to uneven surfaces and low-pressure sealing environments. It’s commonly used in automotive, HVAC, and construction applications for sealing, cushioning, and insulating tasks.

    Frequently Asked Questions About Semi-geschlossenzelliges EPDM

    Curious about how semi closed cell EPDM compares to other foams? We’ve compiled the most common questions to help you understand its unique strengths and how best to apply it.

    • What are the main benefits of EPDM foam?

      EPDM foam offers excellent resistance to weathering, UV, ozone, and temperature extremes, making it ideal for outdoor sealing applications.

    • Is EPDM foam suitable for automotive or HVAC sealing?

      Yes. RGH commonly supply EPDM into automotive door seals, HVAC units, and enclosure gasketing due to its long-term durability and compression-set resistance.

    • How well does EPDM foam resist oils and fuels?

      EPDM provides poor resistance to oils, fuels, and hydrocarbons. For oil exposure, neoprene or NBR-based foams are typically recommended.

    • Does EPDM foam accept PSA adhesives?

      Yes. EPDM bonds very well with high-performance acrylic adhesives and RGH commonly supply with adhesive backing for easy installation.

    • What densities and thicknesses are available?

      EPDM foams come in a several densities and can be supplied in thicknesses from thin gasketing layers to thick sealing strips. Custom die-cutting and lamination are standard for RGH.
