Medium Cellular Silicone HT-800
HT-800 is a highly versatile, medium firmness silicone that offers the lightness of a foam, with the enhanced sealing capabilities of a traditional sponge rubber. It is used to seal and protect various outdoor communication, electronics, and lighting enclosures, while providing protection against wind-driven rain and fire. The material is also used to reduce shock or isolatevibration.
Features and Benefits
Good 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 and unique formulation provides enhanced sealing performance to resist penetration of fine particles and wind-driven rain.
Applications
Environmental seals to protect against penetration of dust, moisture, air, or light within outdoor enclosures such as lighting fixtures, HVAC units, and electronic cabinet
Vibration isolators in electronic components and transportation vehicles
Shock absorbing cushions and gaskets
Installation
Available with a pressure-sensitive adhesive on one or two sides to allow easy application to a variety of surfaces.
