Abstract
The invention relates to a thermal interface material, such as thermally conductive pads or thermally conductive sheets, exhibiting good elongation properties, the material being based on an elastomer matrix comprising from 85 to 100 phr of silicone rubber exhibiting a weight-average molar mass, Mw, within a range extending from 150 to 1000 kg/mol; from 250 to 1000 phr of a thermally conductive filler, the thermally conductive filler comprising more than 50% by weight of alumina with respect to the total weight of thermally conductive filler; from 15 to 150 phr of silicone oil exhibiting a viscosity at 25° C. of less than 150 000 mPa·s; and from 0.2 to 5 phr of a crosslinking agent.
