In this work, devulcanized rubber obtained from a thermo-mechanical devulcanization process with supercritical carbon dioxide was utilized in a virgin tire compound in order to lower the material cost. Different content of devulcanized rubber from 10 phr to 30 phr was used as part of the rubber in an actual virgin tire compound. Curing characteristics, Mooney viscosity, tensile strength, tear strength, elongation at break, and hardness of different samples were measured in order to evaluate the impact of incorporation of devulcanized rubber in a virgin tire compound. The results show that up to 30 phr devulcanized rubber can be used in a virgin tire compound without any significant deteroriation in compound properties.
