AirSil™ Silicone foam rubber is the ideal solution for all applications requiring a highly compressible, low-density material.

AirSil™ is available in several densities and hardnesses.

AirSil™ Silicone foam also offers the many exceptional properties that make it such a high performer. AirSil™ FR with flame retarding agent.

We can provide seal strips or other custom extruded forms: solid or hollow,cord, round or square, etc. to your specifications. Formed and cut to your desired length. Certain additives can be added to the material formulation per your engineering application.

Benefits of Silicone Foam

  •  Low density, excellently suited for use in lightweight construction
  •  Good acoustic and thermal insulation
  •  Flame resistance
  •  No release of toxic gas on thermal decomposition
  • Closed-cell foam
  • Low compression set
  • Flexible seal with high UV, chemical and weather resistance
  • High heat resistance, service temperatures from -50 to +200 °C with no appreciable change in elastic properties

    AirSil™ applications include

    • gaskets
    • heat shields
    • fire stops
    • seals
    • cushions
    • insulation for a wide variety of products/ applications


    • resistant to temperature extremes
    • resistant to UV
    • resistant to ozone
    • extremely resilient to mechanical fatigue
    • excellent compression-set and creep resistance
    • meet the most stringent UL flame ratings


We also provide Nitrile Foam for insulation, cushion,shock/vibration/sound absorption: InGel™ and ViSorb™. Ideal for lamination: PSA, laser/water jet cutting.
