RECLAIMED RUBBER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reclaimed rubber having excellent vulcanized property of matter and its manufacturing method in the reclaimed rubber obtained by desulfurization treatment. SOLUTION: In the reclaimed rubber obtained by the desulfurization treatment of a vulcanized rubber, a ratio of sol in the reclaimed rubber is 80% or more and peak top molecular weight of the sol as determined by gel permeation chromatography (GCP) is 100,000 or less.
