Title (EN) RUBBER COMPOSITION, PRODUCTION METHOD THEREFOR, AND TIRE
(FR) COMPOSITION DE CAOUTCHOUC, PROCÉDÉ DE PRODUCTION ASSOCIÉ ET PNEUMATIQUE
(JA) ゴム組成物及びその製造方法、並びにタイヤ
Abstract:
(EN) Provided is a rubber composition capable of giving rubber articles, e.g., tires, which have an improved on-ice performance while satisfactorily retaining wear resistance. The rubber composition is characterized by comprising a rubber component and fibrous or flat particles, at least some of the particles, in the rubber composition, being present as a plurality of agglomerates, 70% or more of which have an agglomerate diameter of 10-1,000 μm.
(FR) L'invention concerne une composition de caoutchouc en mesure de donner des articles en caoutchouc, par exemple des pneumatiques, qui présentent une performance améliorée sur glace, tout en conservant de manière satisfaisante une résistance à l'usure. La composition de caoutchouc est caractérisée en ce qu'elle comprend un constituant de caoutchouc et des particules fibreuses ou plates, au moins certaines des particules, dans la composition de caoutchouc, étant présentes sous la forme d'une pluralité d'agglomérats, dont 70 % ou plus présentent un diamètre d'agglomérat de 10-1000 µm.
(JA) タイヤ等のゴム物品の耐摩耗性を良好に維持しつつ、氷上性能を向上させることが可能なゴム組成物を提供する。ゴム組成物は、ゴム成分と、繊維状又は扁平状の粒子とを含み、前記粒子が、ゴム組成物中で複数の凝集塊を構成し、前記複数の凝集塊のうち、凝集径が10μm以上1000μm以下である凝集塊の割合が、70%以上である、ことを特徴とする。
