BF2000 Silicone Sponge

BF2000 is an ultra-soft, highly compressible silicone foam. The combination of low weight and softness makes this flame-retardant foam ideal for transportation, industrial and electronic applications where low closure force and sealing are critical.

Available from stock in black, rolls are 6mtrs long x 915mm wide and available in 3.2mm, 4.8mm, 6.4mm, 9.5mm, 12.7mm thick. CB Frost can supply BF2000 as rolls or convert into strip/tape or die-cut shapes. For more information, please contact one of our sales team or visit the capabilities section of our website.

Features and benefits

  • Ultra-low softness allows designers to use less force to seal enclosures and still protect devices from the environment
  • Resistant to ultraviolet light, ozone, extreme temperatures
  • Excellent memory and low stress relaxation reduce maintenance costs associated with gasket failure
  • High compressibility allows the material to conform to variable width gaps, allowing more design flexibility

BF2000 has been tested to several standards and is widely used in the Mass Transit industry. Below are some of the standards the material has been tested to.
