Abstract
A thermal conductive silicone composition is provided. The composition comprises: (A) an organopolysiloxane having at least two silicon atom-bonded alkenyl groups with 2 to 12 carbon atoms per molecule; (B) an organopolysiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; (C) an organopolysiloxane having at most two silicon atom-bonded hydrogen atoms per molecule; (D) an aluminum hydroxide powder, such as a mixture of an aluminum hydroxide powder having an average particle size of at least 0.1 μm and less than 5 μm and an aluminum hydroxide powder having an average particle size of 5 μm to 50 μm; and (E) a hydrosilylation reaction catalyst. The composition cures to form a thermal conductive soft material. The material generally has little to no change in hardness even if the composition is cured after long-term storage.
