Modified Lignin: LG Series — Carbon Reduction, Aging Resistance, Lower Rolling Resistance, and Low Heat Generation

☘Overview: GreenThinking® LG Series is a high-performance, eco-friendly reinforcing agent based on 100% natural plant lignin. Through nano-modification and activation of lignin’s reactive groups, it is specifically designed for green tires and rubber products. It exhibits excellent dispersion and compatibility with rubber matrices, enabling partial or full replacement of traditional reinforcing agents (e.g., silica, carbon black). It enhances reinforcement while imparting aging resistance, adhesion, tear resistance, and reduced carbon emissions. Sourced from renewable plant biomass, lignin aligns with global carbon neutrality goals.

☘Applications:

GreenThinking® LG Series is suitable for key tire components and scenarios:

• Tread Reinforcement: Replaces partial carbon black/silica, improving aging resistance and reducing rolling resistance.
• Sidewall Anti-Aging: Absorbs UV via aromatic rings and inhibits oxidation via phenolic hydroxyl groups, delaying cracking.
• Inner Liner Gas Barrier: Forms a dense network with butyl rubber, reducing gas permeability.

☘Key Features:

1. High Reinforcement:
   Lignin’s hydroxyl/methoxy groups form hydrogen bonds or crosslinks with rubber molecules, enhancing interfacial bonding. Nano-modification further boosts reinforcement.
2. Superior Aging/UV Resistance:
   Phenolic hydroxyl groups scavenge free radicals, suppressing oxidative chain reactions and mitigating UV-induced hardening/cracking.
3. Enhanced Adhesion:
   Polar groups (e.g., phenolic hydroxyl) form hydrogen/chemical bonds with fibers/metal, improving rubber-to-reinforcement adhesion.
4. Reduced Rolling Resistance & Heat Buildup:
   Optimized viscoelasticity minimizes internal friction during dynamic deformation. Lignin particles reduce irreversible polymer chain slippage, lowering hysteresis loss.
