GreenThinking® NSA04 is a functional material composed of nano-silicon aluminum alloy (AlSiO3·H2O), specifically designed to enhance the wet grip, wear resistance, and rolling resistance performance of tires. The mechanism of nano-silicon aluminum alloy mainly lies in its unique physicochemical properties, which can pierce the water film between the tire and the road surface, thereby improving the tire’s grip on wet roads. This material can form a good interfacial bond with the rubber matrix, enhancing the rubber’s wear resistance, reducing heat generation, and improving fatigue resistance. The application of nano-silicon aluminum alloy is extensive, suitable for various types of tires, including passenger car tires, commercial vehicle tires, and high-performance racing tires. In high-performance tires, the use of nano-silicon aluminum alloy can significantly improve the comprehensive performance of tires, providing better grip and wear resistance on wet roads while reducing rolling resistance and improving fuel economy.
