Applications of devulcanized rubber made from truck tyres

Devulcanized rubber (DvR) is used as a partial substitution for rubbers in recipes for various rubber goods. In the lecture, several examples of the application of DvR are shown, the most demanding is a partial substitution of virgin rubber in recipes for tractor tyres. The recommended portion of DvR are discussed considering the changes of ultimate properties, as well as the possible modifications of DvR containing blends by fillers, additives, and optimizing the vulcanization systems.
