Research progress on sustainability of key tire materials

In recent years, countries worldwide have engaged actively in the research and development of green and sustainable materials in the face of the increasing depletion of petroleum resources, the need to reduce material waste, and the environmental pollution caused by the various types of waste. In the tire industry, the key materials for the various components of tires are mostly dependent on petroleum resources. Development of green tires and green processing technologies using sustainable materials is an important development direction for the future of the tire industry, and many tire-manufacturing companies have proposed their visions for the development of eco-friendly tires. Rubber, cord fabric, and additives are the main materials used in tire manufacturing. This article summarizes the research status of the green materials that can meet the requirements of environmental friendliness and sustainability, replace traditional materials, and reduce petroleum resource consumption in existing tire production. These materials mainly include natural rubber or bio-based synthetic rubber, green renewable cord fabrics, and green processing additives. The prospects for the application of these new green materials in tire manufacturing are also discussed.
