In tire manufacturing, dynamic heat buildup and vulcanization reversion remain critical bottlenecks—accelerating wear, increasing rolling resistance, and compromising safety. Sane ZenChem’s GreenThinking® AF28 Tire Anti Fatigue Agent delivers a scientifically engineered solution. As leading Tire Anti fatigue agent Manufacturers in China, we combine molecular innovation with industrial-scale precision to redefine tire performance and longevity.
Core Mechanism: Dual-Action Bond Optimization
AF28 targets natural rubber (NR) systems through covalent anchoring:
- Terminal Group Modification: Reacts with NR chain ends (–OH, –C=O) and carbon black surface groups (carboxyl, phenolic), enhancing polymer-filler bonding.
- Polysulfide Stabilization: Reduces thermal degradation of cross-links by 40%, preventing vulcanization reversion at high temperatures (151°C+).
This dual action minimizes filler-network friction, slashing hysteresis loss and energy dissipation.
Performance Advantages
- 35% Lower Dynamic Heat Generation
Optimizes carbon black dispersion via van der Waals/hydrogen bonding, reducing Payne Effect. RPA tests confirm hysteresis loss reduction at 60°C. - 20% Reduced Rolling Resistance
Improves tan δ at 60°C (GB/T 16584-1996), enhancing fuel efficiency without compromising wet grip. - 30% Extended Tire Lifespan
Prevents reversion-induced cross-link breakdown. Post-aging tests show retained tensile strength (+10%) and elasticity. - Accelerated Vulcanization
Shortens curing cycles by 15% at 151°C×60min, boosting production efficiency. - Mechanical Integrity
Increases hardness and constant elongation stress while maintaining abrasion resistance.
Technical Validation
- Reversion Resistance: AF28 stabilizes polysulfide bonds (S–S–S), maintaining cross-link density after 48h/100°C aging.
- Dynamic Stiffness: Reduces Kd/Ks ratio from 1.46 to 1.34 in damping products (AF27 variant data).
- Processing: Dosage at 1–1.6 phr during NR mixing maximizes efficacy.
