Abstract:
(EN) An electrically conductive thermoplastic elastomer composition which contains carbon black in an amount of 10 to 100 parts by mass inclusive relative to the total amount, i.e., 100 parts by mass, of a mixture composed of an ethylene rubber having a Mooney viscosity (ML1+4, 100ºC) of 40 or less and a propylene elastomer, wherein the ethylene rubber is crosslinked and the composition has a storage modulus of 500 MPa or less at -10ºC and also has a volume resistivity of 1 Ω·cm or less.
(FR) La présente invention concerne une composition d'élastomère thermoplastique électriquement conductrice qui contient du noir de carbone en une quantité de 10 à 100 parties en masse inclus par rapport à la quantité totale, c'est-à-dire, 100 parties en masse, d'un mélange composé d'un caoutchouc éthylène ayant une viscosité Mooney (ML1+4, 100 °C) de 40 ou moins et un élastomère de propylène, le caoutchouc éthylène étant réticulé et la composition présente un module de conservation de 500 MPa ou moins à -10 °C et présente en outre une résistivité volumique de 1 Ω.cm ou moins.
(JA) ムーニー粘度(ML1+4、100℃)が40以下のエチレン系ゴムとプロピレン系エラストマーからなる混合物の合計100質量部に対して、カーボンブラックを10質量部以上100質量部以下含み、前記エチレン系ゴムが架橋されており、-10℃における貯蔵弾性率が500MPa以下であり、体積抵抗率が1Ω・cm以下である導電性熱可塑性エラストマー組成物。
