Abstract
The invention concerns a method of devulcanising vulcanised rubber which comprises the following steps: a) providing at least one vulcanised rubber composition; b) grinding the vulcanised rubber into chips or pellets; c) mixing the ground rubber obtained from step b) in such a way as to homogenise the form and temperature of same. d) carrying out a non-degrading mechanical treatment on the mixed rubber at the end of step c) to obtain a polymeric composite. The invention also concerns a thermoplastic material and an elastomeric mixture which comprise, in the formulation of same, at least one polymeric composite obtained by this method of devulcanisation.
