VULCANIZED RUBBER CONVERSION

摘要

Vulcanized rubber, for example from used tires, can be devulcanized to provide a reaction product that has similar rheological properties to the original un-vulcanized rubber. The vulcanized rubber is processed at a temperature that is less than a critical temperature of a solvent, such as water or water and alcohol. The process is carried out at a pressure that is higher than the vapor pressure of the solvent.
