Weak Link Vulcanization: A New Approach to Lower Temperature, Higher Efficiency Crosslinking

Case 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.
 

Applications:

  • Tire rubber vulcanization


Advantages:

  • Improved solubility in tire rubber precursors compared to elemental sulfur and improved crosslinking
