Gap Fillers

Gap Filler CircuitboardThe ThermaCool family of high performance thermally conductive gap fillers provides solutions to difficult thermal management problems. These products can be used to fill gaps and enhance thermal performance of the electrical system. ThermaCool gap fillers can accommodate materials of different coefficients of thermal expansion with the compliant interface. The ThermaCool gap filler family includes products in a variety of thicknesses and a range of hardness values to effectively close gaps while providing the thermal transfer needed in demanding electronic applications.

R10404 Series
Saint-Gobain Performance Plastics ThermaCool® R-10404 is a thermally conductive closed cell silicone sponge rubber. This material offers thermal conductivity along with electrical isolation. R-10404 is the superior choice for gasketing and cushioning applications requiring critical thermal transfer sealing.

TC100 Series
Saint-Gobain Performance Plastics ThermaCool® TC100 is an unsupported thermally conductive solid silicone rubber. This material offers thermal conductivity along with electrical isolation for heat transfer applications between PC boards and heat sinks. TC100 can be used to fill air gaps between PC boards and heat sinks.

TC3005 Series
Saint-Gobain Performance Plastics ThermaCool® TC3005 is a high performance gap filler product. It is a low modulus thermally conductive silicone rubber filled with thermally conductive, electrically isolating material. It is extremely conformable, naturally tacky and hence results in very low thermal resistance values. The product is available with fiberglass or aluminum foil reinforcement.
