Soft Cellular Silicone IOTA-HT-870
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 and Benefits
Good memory and
low stress relaxation reduces maintenance costs associated with gasket failures
due to compression set and softening.
Softness allows
designers to use less force to seal enclosures and still protect their device
from the environment.
High compressibility
allows material to conform to variable width gaps and awkward shapes, thereby
allowing engineers more design flexibility.
Resistance to
ultraviolet light, ozone, extreme temperatures, and flame
enables consistent performance
in all environments.
Available through
distribution sites throughout North America, Europe, and Asia.
Applications
Environmental seals to
protect against penetration of dust, moisture, air, or light within outdoor enclosures
such as lighting fixtures, HVAC units, and electronic cabinets.
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.
