Features and Benefits of BISCO® BF-1000:

  • Excellent memory and low stress relaxation reduces maintenance costs associated with gasket failures due to compression set and softening.
  • Softness allows designers to use less force to seal enclosures and still protect their device from the environment.
  • High compressibility allows the material to conform to variable width gaps and awkward shapes, thereby allowing engineers more design flexibility.
  • Resistance to ultraviolet light, ozone, extreme temperatures, and flame enables consistent performance in all environments.
  • Available through distribution sites throughout North America, Europe, and Asia.
  • FDA compliant in accordance with FDA Regulation 21 CFR 177.2600.


  • Environmental seals to protect against penetration of dust, moisture, air or light within outdoor enclosures such as lighting fixtures, HVAC units, and electronic cabinets
  • Vibration isolation in electronic components and transportation vehicles
  • Fire retardant thermal insulation


  • Available with a pressure-sensitive adhesive on one or two sides to allow easy application to a variety of surfaces.
