Silicone thermal insulation stops or slows the spread of heat. and typically has a cellular structure with tiny air-filled pockets.
Because air has a relatively low thermal conductivity, it serves as a thermal barrier and reduces the rate at which heat is transferred.

Advantages of Silicone Insulation
Silicone is one of the many gasket materials that ISP die cuts, and its applications aren’t limited to environmental sealing. Silicones resist water and dust, but their ability to withstand higher temperatures distinguishes them from other elastomers that can also be used for environmental sealing and thermal insulation.
Among their advantages, silicones maintain their mechanical properties and resist compression set even after exposure to high heat. They are also chemically inert and have good dielectric properties. This enables silicone’s use in demanding applications with multiple requirements, such as thermal insulation in environments with high voltages and coolants.
ISP Capabilities
At ISP, we can convert silicone insulation from material suppliers such as Rogers Corporation, which manufactures BISCO® silicone sponge, and Saint-Gobain, which manufactures Norseal® silicone foam. We also convert customer-supplied materials and provide value-added services, such as pressure-sensitive adhesive (PSA) lamination for peel-and-stick solutions.
From prototyping through production, ISP can be an extension of your engineering team
