Industry Pain Points and Challenges
1. Thermal Degradation and Sulfur Reversion in Rubber
Rubber products, especially those used in high-temperature environments (e.g., tires, conveyor belts, and shock absorbers), face severe thermal degradation and sulfur reversion. For engineers searching for the best rubber anti-reversion agent for tires, this is a critical challenge. During vulcanization, polysulfide bonds break under heat, leading to:
- Loss of crosslinking density
- Reduced mechanical properties (tensile strength, elongation)
- Increased rolling resistance in tires – a key concern for those looking to reduce rolling resistance
- Poor aging resistance
2. Dynamic Fatigue and Performance Loss
Rubber components subjected to repetitive stress (e.g., tire sidewalls, motor mounts) suffer from:
- Dynamic stiffness increase → Harsh ride quality
- Creep deformation → Dimensional instability
- Metal-rubber bonding failure → Premature tire damage (highlighting the need for rubber-to-metal bonding improvement)
3. Compromised Durability in High-Temperature Applications
Conventional rubber formulations struggle with:
- Hot air aging (70°C–100°C) causing hardness spikes and strength loss – a problem solved by high-performance rubber crosslinking solutions
- Compression set issues leading to permanent deformation
Solution: GreenThinking® RT88 – The Ultimate Rubber Stabilizer
1. Stable Crosslinking Structure for Superior Heat Resistance
For manufacturers wondering how to improve rubber thermal stability, GreenThinking® RT88 forms thermodynamically stable carbon-sulfur bonds during vulcanization, combining:
- Mono-sulfide/di-sulfide stability (resists reversion)
- Polysulfide flexibility (maintains dynamic performance)
Data Proof:
- 70°C aging tests show -7.6% elongation loss (vs. -17.4% in blanks).
- 100°C aging reduces tensile strength loss by 9.4% (RT88: -15.5% vs. blank: -24.9%).
2. Anti-Sulfur Reversion Performance
As the best rubber anti-reversion agent for tires, RT88 compensates for broken polysulfide bonds, maintaining crosslinking density under over-vulcanization.
Key Metrics:
- Compression set improvement: 16.09% (RT88) vs. 18.09% (blank).
- Hot air aging resistance: Hardness change reduced to +5 points (vs. +6 in blanks).
3. Dynamic Performance Enhancement
- 3.4% reduction in dynamic stiffness → Smoother vibration damping.
- 16.5% lower creep index → Better dimensional stability.
Metal bonding strength preserved → Critical for rubber-to-metal bonding improvement.
4. Rolling Resistance Reduction for Tires
RT88’s optimized crosslinking network helps reduce rolling resistance by:
- Lowering hysteresis → Fuel efficiency improvement.
- Extending tire lifespan under high-speed conditions.
