World class silicones for worldwide solutions

Thermally Conductive Silicone Adhesive Sealants


Product Listing

SILCOTHERM® silicone adhesives make excellent thermally conductive materials through the addition of specialist fillers. Heat can be dissipated effectively from processors, power units, LED's and any other components to improve performance and product life. They can also be used to improve heat conduction in sensors, radiators and other thermal devices.

ACC Silicones have developed a range of high thermally conductive materials using their patented silicone technology for specialist electronic applications. The liquid nature of the materials reduces air gaps and further increases the effective dissipation of heat when compared with other preformed materials.
