Cradle-to-cradle approach to waste tyres and development of silica based green tyre composites

This work is about simultaneous devulcanization and chemical functionalisation of waste styrene butadiene rubber vulcanizate (SBR) using thermo-mechanical treatment and sulphide based multifunctional devulcanizing agent. The as-grown compounds are reinforced with nano-silica and re-vulcanized to prepare rubber composites. The curing and processing characteristics, and mechanical performance are further compared with those of conventional silica...
