Title:
THERMALLY CONDUCTIVE GREASE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/070068
Kind Code:
A1
Abstract:
The present invention pertains to a thermally conductive grease composition containing a matrix resin and a thermally conductive filler. The matrix resin contains: liquid dimethylpolysiloxane (A) having a kinematic viscosity of 100-10,000 mm2/s at 40ºC; and an ethylene-propylene copolymer (B) having a kinematic viscosity of 1-10,000 mm2/s at 40ºC. When the total amount of the liquid dimethylpolysiloxane (A) and the ethylene-propylene copolymer (B) is 100 parts by mass, the matrix resin contains 50-97 parts by mass of the liquid dimethylpolysiloxane (A) and 3-50 parts by mass of the ethylene-propylene copolymer (B). The thermally conductive grease composition according to the present disclosure contains 400-2,500 parts by mass of the thermally conductive filler with respect to 100 parts by mass of the total amount of the liquid dimethylpolysiloxane (A) and the ethylene-propylene copolymer (B).
