Iota Silicone Oil (Anhui) Co., Ltd
Description
IOTA HT-820 is a 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. IOTA Silicone oil are available in various thicknesses and manufactured in roll form to allow fabricators to easily convert the material to the proper dimensions.
Features & Benefits
1. Excellent memory and low stress relaxation reduces maintenance costs associated with gasket failures due to compression set and softening.
2. Resistance to ultraviolet light, ozone, extreme temperatures, and flame enables consistent performance in all environments.
3. Compact cell structure provides improved sealing performance.
Applications
1. Environmental seals to protect against pentration of dust, moisture, air, or light within outdoor enclosures such as lighting fixtures, HVAC units, and electronic cabinets.
2. Enclosures requiring a more durable, high closure force gasket.
Installation
Available with a pressure-sensitive adhesive on one or two sides to allow easy application to a variety of surfaces.
