RUBBER COMPOSITION USING RECOVERED CARBON BLACK

摘要

PROBLEM TO BE SOLVED: To obtain a recovered carbon black which can be recovered from a rubber composition in general and has characteristics equal or superior to those of a carbon black used as a raw material, and a rubber composition which contains the recovered carbon black and is excellent in damping properties. SOLUTION: The recovered carbon black is obtained by subjecting a rubber composition at least containing a rubber and a carbon black to a decomposition treatment. The rubber composition contains the recovered carbon black and a rubber and/or a resin.
