Abstract:
(EN) A rubber composition for torsional dampers that has (A) a minimum value of tanδ at -30°C to 120°C of 0.140 or greater, (B) a value of tanδ at -30°C which is up to 3.5 times that at 60°C, and (C) a value of E' at -30°C which is up to 21 times that at 60°C.
(FR) L'invention concerne une composition de caoutchouc pour amortisseurs de torsion qui présente (A) une valeur minimale de tanδ, à une température de -30 °C à 120 °C, supérieure ou égale à 0,140, (B) une valeur de tanδ, à une température de -30 °C, qui est jusqu'à 3,5 fois celle à une température de 60 °C, et (C) une valeur d'E' à une température de -30 °C qui est jusqu'à 21 fois celle à une température de 60 °C.
(JA) トーショナルダンパー用ゴム組成物は、(A)-30℃~120℃におけるtanδの最小値が0.140以上、(B)-30℃におけるtanδが60℃対比で3.5倍以下、及び(C)-30℃におけるE'が60℃対比で21倍以下、である。
