TREATMENT OF CROSS-LINKED ELASTOMERS

摘要

A method of treating (recycling) cross-linked elastomeric material comprises, subjecting the material to mechanical stresses in a processing apparatus to mechanochemically de-vulcanise a portion of the material. The processing operation is controlled such that a predetermined portion of the untreated material remains vulcanised as granules, to thereby produce a flowable material comprising granules of vulcanised elastomer disperses in a matrix of de-vulcanised elastomer.
