Reclaimed rubber and process for reclaiming vulcanized rubber

摘要

Reclaimed rubber for reuse in tires or for asphalt, etc. and obtained by devulcanization treatment of vulcanized rubber from discard tires, etc. has a proportion of sol to gel of 10-80%, a weight-average molecular weight (Mw) of the sol by gel permeation chromatography (GPC) of 20,000-300,000, and a degree of swelling of the gel of 3.0-20.0. A process for reclaiming the vulcanized rubber is also disclosed.
