Abstract:
A method of reclaiming a cured elastomer material in the form of crumb or chips, comprising mixing the elastomer material with a devulcanization-aiding chemical composition and performing devulcanization by applying a shear-stress deformation while performing a mechanical disintegration into fine-ground crumbs under a controllable temperature not exceeding about 90 degrees C.
