About
Weak Link Vulcanization: A New Approach to Lower Temperature, Higher Efficiency Crosslinking Tech ID: UA17-176 Invention: A new high sulfur content polymer has been developed for tire vulcanization. This polymer may improve chemical compatibility, mixing, and result in more efficient crosslinking. Background: Sulfur, the traditional vulcanizing agent for tire rubber, is largely insoluble in rubber precursors and requires high temperatures to form crosslinks. Even with high temperatures, the crosslinking may be suboptimal with respect to addition of crosslinking agent. Status: issued U.S. patent #11,674,005
Key Benefits
Improved solubility in tire rubber precursors compared to elemental sulfur and improved crosslinking
Applications
Tire rubber vulcanization
