Rogers BISCO HT-800 Medium Cellular Silicone offers the lightness of foam with the enhanced sealing capabilities of sponge rubber.
BISCO HT-800 Medium Cellular Silicone is a versatile, medium-firmness silicone.
HT-800 silicone foam leads the market in sealing and protecting outdoor communication, electronics, and lighting enclosures.
HT-800 silicone foam's superb memory and low-stress relaxation reduce maintenance costs from gasket failures caused by compression set and softening. Its compact cell structure and unique formulation provide enhanced sealing against penetration from fine particles and wind-driven rain and fire.
It also offers shock reduction and vibration isolation in electronic components and transportation vehicles.
