Rogers BISCO HT-840 Extrafester Silikonschaum

HT-480 is an extra-firm grade silicone foam that offers improved durability and sealing. It is used to seal and protect various outdoor communication, lighting, and electronic enclosures from small dust particles, wind-driven rain, and fire. It offers a higher tear and tensile strength than our lighter grade foams. BISCO® Silicones are available in various thicknesses and manufactured in roll form to allow fabricators to easily convert the material to the proper dimensions.


  • 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.
  • Compact cell structure provides improved sealing performance.
  • Available through distribution sites throughout North America,Europe, and Asia.


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