Rogers Corporation Bisco® BF-2000 Ultra-Soft Silicone Foam
Categories: Polymer; Thermoset; Silicone; Silicone Foam

Material Notes: BISCO® Ultra Soft is a highly compressible silicone foam. The combination of low weight and softness makes this flame retardant foam ideal for transportation, industrial and electronics applications where low closure force and dust sealing are critical. Available in various thicknesses and manufactured in roll form.

Features and Benefits:

  • Ultra low softness allows designers to use less force to seal enclosures and still protect their device from the environment.
  • High compressibility allows material to conform to variable width gaps, thereby allowing more design flexibility.
  • Excellent memory and low stress relaxation reduces maintenance costs associated with gasket failures due to compression set and softening.
  • Resistance to ultraviolet light, ozone, extreme temperatures and flame enables consistent performance in all environments.
  • Color: black
  • Thickness: 0.125 in to 0.500 in
  • Standard Width: 0.500 in to 36.0 in


  • Vibration isolation in electronic components and transportation vehicles
  • Low closure force gaskets within portable electronics such as laptops and LCD screens within aircraft and rail interiors
  • Fire retardant thermal insulation
