Title
(EN) RESIN MOLDED PRODUCT
(FR) PRODUIT MOULE EN RESINE
Abstract
(EN)
A resin molded product exhibiting a higher conductivity than that which can ordinarily be expected of the content of a conductive filler, especially a low surface resistance. This resin molded product contains a matrix of a resin material and a conductive filler dispersed in the matrix. The content of the conductive filler is set to less than 20 wt. %, and a voltage of 20 kV or higher and lower than a breakdown voltage of the matrix is applied. The conductive filler is made of fibers such as carbon fibers or graphite fibers having an average diameter of 0.002 to 15 microns, for example. This resin molded product usually contains a coloring agent dispersed in the matrix together with the conductive filler and presents a color according to that coloring agent.
(FR)
L'invention se rapporte à un produit moulé en résine présentant une conductivité supérieure à celle à laquelle on peut généralement s'attendre avec une charge conductrice, et possédant en particulier une faible résistance de surface. Ce produit en résine moulé contient une matrice d'un matériau de type résine et une charge conductrice dispersée dans la matrice. La charge conductrice est présente en quantité représentant moins de 20 % en poids et l'on applique une tension supérieure ou égale à 20 kV et inférieure à une tension de claquage. La charge conductrice est composée de fibres telles que des fibres de carbone ou des fibres de graphite ayant un diamètre moyen compris entre 0,002 et 15 microns, par exemple. Ce produit moulé en résine contient généralement un agent de coloration dispersé dans la matrice et associé à la charge conductrice et il présente un aspect coloré que lui confère ledit agent de coloration.
