Market Demand for Advanced Rubber Reinforcing Fillers
Traditional reinforcing fillers like carbon black and silica have long been the industry standard. However, with the rise of electric vehicles, high-performance tires, and energy-efficient machinery, new challenges have emerged: heat build-up, rolling resistance, and durability under extreme conditions. A thermally conductive rubber filler that also offers high wear resistance is becoming essential for modern rubber formulations. The GreenThinking® NSA series meets this need by providing a unique combination of properties that traditional fillers cannot match.
As a trusted high purity reinforcing filler manufacturer China and a premier Rubber Functional filler Manufacturers China, we have developed these materials to help rubber compounders achieve:
- Lower compression heat build-up
- Reduced rolling resistance
- Enhanced modulus and thermal conductivity
- Improved wear and aging resistance
- Excellent chemical stability
Our product is specifically engineered as a Rubber additive to reduce tire rolling resistance and as Rubber chemicals to improve tire wear resistance, making it an indispensable component in high-performance tire formulations.
Product Spotlight: GreenThinking® NSA25 and NSA26
The GreenThinking® NSA25 and NSA26 series are high-purity reinforcing fillers derived from specialty silicon-aluminum alloys. They are engineered to remain chemically inert even in the presence of catalysts or multi-component systems, and they maintain their integrity under extreme temperatures and harsh environments. With high thermal conductivity and high Mohs hardness, these materials serve as ideal wear resistant reinforcing agents for demanding rubber applications. As a thermally conductive wear resistant filler for tires, they are particularly effective in tire treads, sidewalls, and undertread compounds, where they reduce heat buildup and improve durability. They also function as a premier wear resistant filler for rubber compound in industrial products such as conveyor belts and rollers.
Key Features and Benefits
- High Thermal Conductivity – Effectively dissipates heat, reducing compression heat build-up by 12.5–21% in tire compounds.
- Low Rolling Resistance – Contributes to 11.6–17.5% lower rolling resistance, improving fuel efficiency and EV range.
- Exceptional Wear Resistance – Acts as a powerful wear resistant reinforcing agent to extend product service life.
- Chemical Inertness – Does not catalyze degradation or react with other compounding ingredients.
- High Whiteness – Enables light-colored and colored rubber products without discoloration.
- Good Reinforcement – Improves modulus and tensile strength while maintaining processability.
As a high thermal conductivity filler, NSA25 and NSA26 are particularly effective in tire treads, sidewalls, and undertread compounds. They also excel in industrial rubber products such as conveyor belts, rollers, and casters where heat and abrasion are critical factors. Their versatility as a Thermally conductive rubber filler makes them suitable for a wide range of polymer systems.
