HT-820

HT-820 is medium cellular silicone offers the lightness of foam with the enhanced sealing capabilities of sponge rubber.
HT-820 silicone foam’s superb memory and low stress relaxation reduces 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.
