A curable particulate silicone composition having hot melt properties, excellent in handling workability such as overmolding and curing properties and giving a cured product excellent in hardness and toughness at room temperature to about 250 ° C., and Provided are pellets and the like obtained by molding the curable granular silicone composition, and uses thereof. [Solution] (A) 100 parts by mass of hot melt silicone fine particles having a softening point of 30 ° C. or higher and having a hydrosilylation reactive group and / or a radical reactive group, (B) inorganic filler (fine particles) 100 to 4000 And a curing agent, and the average linear expansion coefficient in the range of 25 ° C. to 200 ° C. is 30 ppm / ° C. or less, and the storage elastic modulus at −50 ° C. (G ′ − 50 ) and the value ratio of storage elastic modulus (G ' 250 ) at 250 ° C .: (G' -50 / G ' 250 ) is characterized by giving a cured product in the range of 1/1 to 1/50. Curable particulate silicone compositions and uses thereof. |
