SUMMARY

The discussion confirms that there is a process to revulcanize rubber without the need for devulcanization. Specifically, cutting the tire into small pieces and placing them in a mold allows for re-vulcanization at high temperatures. This method enables the reuse of rubber from damaged tires, ensuring that 20-30 pounds of rubber can still be utilized effectively in tire manufacturing.

PREREQUISITES
  • Understanding of rubber vulcanization processes
  • Knowledge of thermoplastic elastomers
  • Familiarity with molding techniques
  • Basic principles of heat treatment in polymer science
NEXT STEPS
  • Research the methods of rubber vulcanization at high temperatures
  • Explore the properties of thermoplastic elastomers
  • Learn about the environmental benefits of recycling rubber materials
  • Investigate advanced molding techniques for rubber processing
USEFUL FOR

Manufacturers in the rubber industry, environmental engineers, and anyone involved in tire recycling and rubber processing will benefit from this discussion.

Does there exist a known process to devulcanize rubber (i.e., getting out all the sulfur crosslinks from the polymer chains) and get out of the process rubber that can be revulcanized? Or does one big slash on a tire mean that 20-30 pounds of rubber can never be used for making tires again?

It'n not necesary to devulcanize the rubber for revulcanized again.
cut the tire in samll pieces and put in a mold. Vulcanize again a hot temperature and finish.
