Tire recycling is a critical component of sustainable waste management, addressing a global challenge of mounting tire waste. The scientific breakthrough enabling efficient tire recycling lies in effective devulcanization, a process that breaks down the hardened, crosslinked structure of vulcanized rubber. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of this field, providing advanced chemical solutions that make tire reprocessing not only feasible but also economically viable.

For R&D scientists and procurement managers, understanding the nuances of tire recycling is key. The core of the problem is the robust sulfur crosslinking achieved during the vulcanization of natural and synthetic rubber, which gives tires their durability. However, this same crosslinking makes them impossible to re-melt and re-mold like thermoplastics. Devulcanization is the chemical or physical process that targets these crosslinks, reverting the rubber to a plastic-like state.

Mechanisms of Advanced Devulcanization

Our leading rubber recycling chemical employs a sophisticated mechano-chemical approach. When waste rubber, typically in granular form (10-40 meshes), is processed with our agent, mechanical energy is applied. This energy, combined with the chemical's action, initiates the breaking of crosslinks:

  • Targeting Crosslinks: The chemical agent works by forming coordination bonds with sulfur atoms within the rubber matrix. This interaction weakens the S-S and S-C bonds, making them susceptible to cleavage under mechanical shear.
  • Minimizing Chain Scission: A crucial aspect of our technology is its selectivity. It primarily targets the crosslinks rather than causing extensive scission (breaking) of the main polymer carbon-carbon chains. This preserves the intrinsic molecular weight and physical properties of the rubber.
  • Process Efficiency: This advanced devulcanization can be achieved at normal temperature and pressure, significantly reducing the energy input required compared to older, high-temperature methods. This also means shorter processing times, enhancing overall efficiency.

Benefits for Tire Reprocessing

The integration of our rubber auxiliary agent into tire recycling processes yields several benefits:

  • Improved Re-processability: The devulcanized rubber becomes pliable and can be easily re-milled, mixed, and molded, making it suitable for a wide range of new applications.
  • Enhanced Mechanical Properties: The revived rubber often exhibits improved break elongation and reduced Mooney viscosity, making it a higher-quality recycled material.
  • Cost-Effectiveness: Significant savings are realized through reduced chemical consumption and improved processing efficiency, making tire recycling more profitable.
