Natural Rubber Vulcanization using Chalcogenide Hybrid Inorganic/Organic Polymers
Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed for tire rubber production. The resulting high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials have improved polymer compatibility and efficient crosslinking. Furthermore, this technology...
