  • V-Ribbed Belt, Production Method Therefor, and Rubber Composition
    Publication number: 20220145962
    Abstract: The present invention relates to a V-ribbed belt including: a tension rubber layer made of a vulcanizate of a rubber composition including a rubber component and short fibers; and a core wire, in which a proportion of the short fibers in the rubber composition is 15-50 parts by mass with respect to 100 parts by mass of the rubber component, and the rubber composition has a minimum Mooney scorch viscosity measured at 125° C. of 70-130.

  • V-RIBBED BELT AND METHOD FOR PRODUCING SAME
    Publication number: 20220099157
    Abstract: A V-ribbed belt includes a compression rubber layer having a frictional power transmission surface that is covered with a fabric. The compression rubber layer includes an inner rubber layer in contact with the fabric and an outer rubber layer on an outer side of the inner rubber layer. The inner rubber layer is formed of a rubber composition having a Mooney Scorch minimum viscosity of 50 to 110 when measured at 125° C., and the outer rubber layer is formed of a rubber composition having a Mooney Scorch minimum viscosity of 70 to 130 when measured at 125° C.
