Abstract
Chemical devulcanization of waste rubber from the automotive industry was carried using benzoyl peroxide as devulcanizing agent and, o-xylene and toluene, as solvents. The effect of time on the process of devulcanizing was investigated. The extent of sulphur removal from the reclaimed rubber was studied by using EDAX technique. Thus, this devulcanized rubber can be blended with virgin rubber and on revulcanizing the mixture, it becomes possible to reuse waste rubber and give it a new life.
Keywords: Devulcanization, waste rubber, o-xylene, toluene, benzoyl peroxide, sulphur removal, EDAX analysis
