Iota Silicone Oil (Anhui) Co., Ltd
Description
Compressibility, softness, and durability allow HT-870 to adapt to various environments, making it an ideal choice for sealing outdoor enclosures, protecting electronics from shock and heat, and providing cushioning or vibration isolation for various applications. IOTA Silicones 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. Softness allows designers to use less force to seal enclosures and still protect their device from the environment.
3. High compressibility allows material to conform to variable width gaps and awkward shapes, thereby allowing engineers more design flexibility.
4. Resistance to ultraviolet light, ozone, extreme temperatures, and flame enables consistent performance in all environments.
Applications
1. Environmental seals to protect against penetration of dust, moisture, air, or light within outdoor enclosures such as lighting fixtures, HVAC units, and electronic cabinets.
2. Shock absorbing cushions and gaskets within automobiles and appliances.
Installation
Available with a pressure-sensitive adhesive on one or two sides to allow easy application to a variety of surfaces.
