Title (EN) THERMALLY CONDUCTIVE SILICONE COMPOSITION AND SEMICONDUCTOR DEVICE
(FR) COMPOSITION DE SILICONE THERMIQUEMENT CONDUCTRICE ET DISPOSITIF SEMI-CONDUCTEUR
Abstract: front page image
(EN)A thermally conductive silicone composition comprises (A) an organopolysiloxane having a viscosity equal to or greater than 100 mPa•s at 25 °C; (B) aluminum powder having an average size of particles ranging from 0.1 to 100 μm; (C) zinc oxide powder having an average size of particles ranging from 0.05 to 50 μm; (D) (i) an organopolysiloxane containing univalent hydrocarbon groups which have unsaturated aliphatic bonds, (ii) an organopolysiloxane containing hydrocarbon groups which are free of unsaturated aliphatic bonds, or a mixture of constituents (i) and (ii); and (E) a silane compound or a product of partial hydrolyzation and condensation of said silane compound. The composition has high conductivity and excellent handleability.
(FR)La présente invention concerne une composition de silicone thermiquement conductrice comprenant (A) un organopolysiloxane ayant une viscosité égale ou supérieure à 100 mPa•s à 25 °C; (B) de la poudre d’aluminium ayant une taille moyenne de particules dans la plage de 0,1 à 100 μm; (C) de la poudre d’oxyde de zinc ayant une taille moyenne de particules dans la plage de 0,05 à 50 μm; (D) (i) un organopolysiloxane contenant des groupes hydrocarbonés univalents qui ont des liaisons aliphatiques insaturées, (ii) un organopolysiloxane contenant des groupes hydrocarbonés qui sont exempts de liaisons aliphatiques insaturées, ou un mélange de constituants (i) et (ii); et (E) un composé silane ou un produit d’hydrolyse partielle et de condensation dudit composé silane. La composition a une conductivité élevée et une excellente maniabilité.
