Title
(EN) HEAT-PROCESSABLE THERMALLY CONDUCTIVE POLYMER COMPOSITION
(FR) COMPOSITION DE POLYMÈRE THERMIQUEMENT CONDUCTRICE QUI PEUT ÊTRE TRAITÉE PAR LA CHALEUR
Abstract
(EN)
The present invention relates to a heat-processable thermally conductive polymer composition comprising (a) 30 to 95 % by weight of a thermoplastic polymer (b) 5 to 40 % by weight of a graphite powder; and (c) 0 to 65 % by weight of optional further component(s), wherein the particles of the graphite powder are in the form of platelets having a thickness of less than 500 nm, and a process for the preparation heat-processable thermally conductive polymer composition.
(FR)
La présente invention porte sur une composition de polymère thermiquement conductrice qui peut être traitée par la chaleur comprenant (a) de 30 à 95 % en poids d'un polymère thermoplastique ; (b) de 5 à 40 % en poids d'une poudre de graphite ; et (c) de 0 à 65 % en poids d'un autre ou d'autres composants facultatifs, les particules de la poudre de graphite étant sous la forme de lamelles ayant une épaisseur de moins de 500 nm. L'invention porte également sur un procédé de préparation d'une composition de polymère thermiquement conductrice qui peut être traitée par la chaleur.
