Viscoelastic Foams

There is no flexible foam application we would not consider. Tell us about your project.

“There is no flexible foam application that we would not consider.”

Although true memory foam originating at NASA, the foam that NASA made is highly inferior to the foam that we produce today and that our foam sells itself based on its quality, characteristics, and price. Viscoelastic foam, or memory foam, is open-cell, flexible polyurethane foam that has a slow recovery that can be controlled by its formulation. In other words, when it is compressed, the foam does not quickly bounce back to its original shape; instead the foam slowly conforms to the shape of and supports the weight of the object compressing it with incomparable comfort, vibration, and shock control. Viscoelastic foam’s structure, mode of function, and slow recovery make it the best material in the world for comfort, shock absorption, and vibration/sound damping applications.

Bergad, “the Visco foam specialists,” offers its Viscoelastic foams in a wide range of physical characteristics, with, but not limited to:

  • Densities from 2 to over 10 pounds per cubic foot,
  • Firmnesses (25% IFD) from 2 to over 300 pounds,
  • Tensile Strengths to nearly 40 psi,
  • Elongations to nearly 200%,
  • Airflows from nearly zero to almost 10 cubic feet per minute,
  • Recovery Rates from extremely slow to extremely fast,
  • Flammability ratings up to and including passing both 14 CFR 25.853(a) Appendix F Part 1 (a) i & ii when tested per Appendix F Part 1 (b) (60 second and 12 second vertical flame tests), California Technical Bulletin 117 (12 second vertical flame test), FMVSS 302 (15 second horizontal flame test), and UL 94 HF-2, UL 94 HBF, UL 94 V-2, UL 94 V-0.
  • and in any Pantone colors.

Some limitations exist in combining the above properties, but feel free to inquire about our capabilities for developing the perfect foam for your needs.

Whether you decide to go with a stock foam or have us develop a foam for your project, we offer our Viscoelastic foams in the following ways:

  • Bun Stock
  • Sheet Stock or Cut-to-size Pieces of Any Size
  • RIM – Reaction Injection Molded Parts
  • Die Cut Parts
  • CNC-shaped Parts
  • OEM parts

We are able to provide very fast lead times at 1 – 14 days for all Viscoelastic bun stock, sheet stock, and cut-to-size pieces. All other lead times vary but are never unreasonable.

Suggested uses for Viscoelastic foams include, but are not limited to:

  • Shock Absorption: Packaging, Safety, Sports Equipment, Military, Product Protection
  • Vibration Damping: Electronics, Industrial, Commercial, Marine, Military, Consumer
  • Sound Attenuation/Damping/Isolation: Electronics, Industrial, Commercial, Marine,
    Military, Consumer, Sound Studio, Speakers, Headphones, Earplugs
  • Sound Transparency: Headset/Headphone ear pieces
  • Seating: Wheelchair, Aircraft, Motor Vehicle of any kind
  • Comfort: Mattresses, Pillows, Medical Products, Ergonomic products, Apparel, Consumer
  • Any Application that Requires the Pulling of a Vacuum on Foam with Subsequent Slow Recovery
  • Any Application that Requires or Could Be Improved with Slow Recovery Foam
  • Any Other Existing or New Applications in Comfort or Shock/Vibration/Sound Control

The markets and industries for Viscoelastic foams include, but are not limited to:

  • Acoustics
