Title (EN) ELECTROMAGNETIC WAVE SUPPRESSION SHEET
(FR) FEUILLE DE SUPPRESSION D'ONDES ÉLECTROMAGNÉTIQUES
(JA) 電磁波抑制シート
Abstract:
(EN) This electromagnetic wave suppression sheet is unlikely to expand when used under high temperature conditions, and exhibits an excellent effect of suppressing electromagnetic waves. The electromagnetic wave suppression sheet comprises, with respect to 100 parts by weight of chlorinated polyethylene: 400-600 parts by weight of magnetic metal powder having an oxide coating formed on the surface thereof; 1-15 parts by weight of a chelating agent; and 1-10 parts by weight of an aging inhibitor.
(FR) La présente invention concerne une feuille de suppression d'ondes électromagnétiques peu susceptible de se dilater lorsqu'elle est utilisée dans des conditions de température élevée, et présentant un excellent effet de suppression d'ondes électromagnétiques. La feuille de suppression d'ondes électromagnétiques comprend, par rapport à 100 parties en poids de polyéthylène chloré : 400 à 600 parties en poids de poudre métallique magnétique comportant un revêtement d'oxyde formé sur sa surface ; 1 à 15 parties en poids d'un agent chélatant ; et 1 à 10 parties en poids d'un inhibiteur de vieillissement.
(JA) 高温環境下で使用した場合でも膨らみが生じ難く、かつ、電磁波抑制効果にも優れる電磁波抑制シート。塩素化ポリエチレン100重量部に対し、表面に酸化被膜が形成された金属磁性粉400~600重量部、キレート剤1~15重量部、老化防止剤1~10重量部が含まれている電磁波抑制シート。
