Green tires, also known as environmentally friendly or low-pollution tires, refer to the replacement of carbon black with high-dispersion precipitated silica in tire formulations, thereby reducing the rolling resistance of the tires, reducing fuel consumption, and achieving environmentally friendly effects of reducing vehicle emissions. Since the 1990s, Michelin has used Rhodia's high-dispersion silica Zeosil 1165MP to launch high-performance green tires. Green tires have been accepted by the public for their comfort, safety, environmental protection and energy saving.
In recent years, the production of green tires using highly dispersed silica has maintained an annual growth rate of 10% to 20%, and more and more original tire indicators have begun to specify the addition of silica. Due to the high requirements for wet traction and rolling resistance of passenger car tires in Europe, green tires are developing rapidly in the European market, and the European Union has already stipulated that green tires must be used for new tires. Therefore, Europe is highly dispersed and precipitated. The region with the highest proportion.
