Newest silicone gap filler offers enhanced options for unique applicationsEngineering360 News Desk | September 30, 2022
Fujipoly America has introduced SARCON GR25B, an advanced silicone, gel-like thermal interface material that delivers a thermal conductivity of 2.5 W/m•K and a popular choice for higher power electronics applications. GR25B is offered in double sticky surfaces, hardened surfaces for easier handling, with polyester mesh to prevent stretching or with both hardened surface and mesh for more complex assemblies.
Depending on application gap size and material thickness, thermal resistance will range from 0.19 K-inch2/W to 1.80 K-inch2/W. The gap filler’s soft consistency gently conforms to uneven surfaces and components to efficiently transfer heat to a nearby heatsink. SARCON GR25B is offered in thicknesses from 0.30 mm to 5.0 mm and can be custom cut to precisely fit the shape needed up to a maximum dimension of 300 mm × 200 mm.
