What is Polyethylene Foam?

Polyethylene (PE) foam is a closed-cell material available in a wide range of densities. Despite being lightweight, it is strong, durable, and resistant to chemicals and aging.

 PE foam does not deteriorate or become brittle over time, making it a reliable long-term solution.

Its closed-cell structure provides excellent water resistance and sealing, making it suitable for both protective and buoyant applications. Easily fabricated, cut, and routed, PE foam is widely used in packaging, insulation, and cushioning solutions across multiple industries.

FAQs

Frequently Asked Questions About Polyethylene Foam

Got a question about polyethylene foam? Explore our FAQs below.

  • What is open cell polyurethane foam typically used for?

    Open cell PU foam is widely used for cushioning, acoustic control, ventilation, filtration, and protective packaging due to its soft, breathable, and flexible structure.

  • Is open cell polyurethane foam suitable for sealing moisture or dust?

    No. Because it has an open, interconnected cell structure, it allows air and moisture to pass through. It is ideal for ventilation and acoustic damping, but not for watertight sealing.

  • Can open cell PU foam be laminated with adhesives or films?

    Yes. RGH laminate PU foam with a range of pressure-sensitive adhesives.

  • Is open cell polyurethane foam fire retardant?

    Fire performance varies by grade. Standard PU foam is combustible, but fire-retardant and UL-listed grades are available depending on application requirements.

  • Can it be die-cut or converted into custom components?

    Absolutely. PU foam is easily cut, slit, profiled, and die-cut into custom geometries for gasketing, sound management, and protective applications.
