What is Polyurethane Foam?

Polyurethane (PU) foam is a open-cell material available in a wide range of densities. PU foam is a versatile material known for its softness, resilience, and ability to be engineered for a wide range of densities and performance characteristics

 Available in multiple densities, PU foam offers excellent compressibility, resilience, and energy absorption. At RGH, we laminate and precision convert PU foams to deliver consistent, application-specific solutions tailored to our customers’ performance and manufacturing requirements.

Benefits

Why Choose Polyurethane Foam?

Polyurethane foam offers an excellent balance of cushioning, durability, and versatility, with properties that can be tailored for noise reduction, protection, insulation, and impact absorption across a wide range of applications.

  • Lightweight Strength

    Despite its strength and durability, PU foam remains lightweight, making it ideal for applications where weight reduction is important .

  • Noise Reduction

    PU foam is effective at reducing noise because its open cell structure absorbs sound energy by trapping and dissipating sound waves, helping to reduce echo, vibration, and airborne noise across a wide range of frequencies>.

  • Durable

    PU foam is a durable material that maintains its cushioning and structural performance over repeated compression, making it well suited for long-term protective and sealing applications.

  • Easy to Fabricate

    RGH can convert PU foam in to many formats including strips, pads, discs or bespoke die cut shapes, kiss cut in to many formats or cut through as individual parts .

  • Protects

    PU foam offers reliable protection and packaging by cushioning products, absorbing shocks, and preventing damage during storage, handling, and transport.

  • Versatile Across Industries

    PU foam is certified for use across a range of industries, including medical, automotive, and other technical applications, meeting the necessary standards for safety and performance.

FAQs

Frequently Asked Questions About Polyurethane 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.
