Abstract:
(EN) In order to provide a rubber composition having excellent crack resistance and high-temperature breaking elongation, this rubber composition is characterized by comprising: a rubber component containing at least 30% by mass of natural rubber and/or a synthetic polyisoprene; and less than 10 parts by mass, relative to 100 parts by mass of the rubber component, of a combination of linear polyhydric alcohol and cyclic polyhydric alcohol.
(FR) Afin de fournir une composition de caoutchouc présentant une excellente résistance à la fissuration et un excellent allongement à la rupture à haute température, la présente invention concerne une composition de caoutchouc caractérisée en ce qu'elle comprend : un constituant caoutchouc contenant au moins 30 % en masse de caoutchouc naturel et/ou un polyisoprène synthétique ; et moins de 10 parties en masse, pour 100 parties en masse du constituant caoutchouc, d'une combinaison d'un polyalcool linéaire et d'un polyalcool cyclique.
(JA) 耐亀裂性及び高温時の破断伸びに優れたゴム組成物を提供することを目的とする。 上記課題を解決するべく、本発明のゴム組成物は、天然ゴム及び/又は合成ポリイソプレンを30質量%以上含むゴム成分と、該ゴム成分100質量部に対して合計10質量部未満の、直鎖状多価アルコール及び環状多価アルコールとを配合してなることを特徴とする。
