BISCO HT-870 Soft Cellular Silicone is ideal for sealing outdoor enclosures, protecting electronics from shock and heat and providing cushioning and vibration isolation. With excellent memory and low stress relaxation, HT-870 silicone reduces maintenance costs from gasket failures caused by compression set and softening. Its extra softness allows designers to use less force to seal enclosures while still protecting devices from the environment. 

Features

  • Available in thicknesses from 0.063 to 0.500 in.
  • Typical density of 15 PCF
  • CFD range of 2-7 PSI
  • Resistant to UV, ozone, extreme temperatures and flame
  • Available with pressure-sensitive adhesive on one or two sides, allowing easy surface application

Benefits

  • Highly adaptable to various environments
  • Softness allows protective seals that use less force
  • High compressibility enables material to conform to variable width gaps, allowing greater design flexibility
  • Reduces maintenance costs associated with gasket failures due to compression set and softening
