Rubber composition comprising pentaerythritol derivative and tire with component thereof

Abstract:

The invention relates to a sulfur curable (and cured) rubber composition which contains one or more pentaerythritol derivatives as pentaerythritol tetrabenzoate (PTB) and/or pentaerythritol tetrakis (3,5-di-tert-butyl-4-hydroxyhydrocinnamate) (PTHC) together with a low molecular weight polyester sebacate. Such combination of materials has been observed to increase resistance to tear for a rubber composition. The invention particularly relates to a tire having a component comprised of such rubber composition.

Abstract(Chinese):

本发明涉及含有一种或多种季戊四醇衍生物作为季戊四醇四苯甲酸酯（PTB）和/或季戊四醇四（3,5-二叔丁基-4-羟基氢化肉桂酸酯）（PTHC）的季戊四醇衍生物（PTHC））的硫可固化（和固化）橡胶组合物与低分子量聚酯癸二酸酯。已经观察到这种材料的组合以增加橡胶组合物的抗撕裂性。本发明特别涉及具有由这种橡胶组合物构成的组分的轮胎。
