Abstract

Thermo-mechanical-chemical devulcanization was carried out on passenger car tire rubber granulate following a new approach. The devulcanization conditions were optimized, and the efficiency was determined as the degree of network breakdown, miscibility and mechanical properties of the de- and revulcanized material. The network was broken by 70%-75%, and tensile strength of 8.6 MPa was achieved. A correlation between tensile strength and total area of undevulcanized particles was established. This devulcanization system is very effective and more sustainable than the conventional ones in terms of environmental hazards and safety.
