Abstract: The present invention relates to a chemical composition of a devulcanizing agent which is used to reclaim waste rubber by mechanical shearing until fine powder is produced. The devulcanizing agent contains two types of components: 1) amino acids, amides or similar carbonyl and amine or amide group containing organic compounds as Reactants for delocalization of sulfur crosslinks and 2) ashless inorganic salts as Anti-Stick additives for subsequent size reduction of rubber particles and preventing them from sticking. In a form of powder the reclaim rubber shows much better technical properties than in a form of sheet, bale or other bulk solid.
