Application
Highly dispersion precipitated Silica usede in green tires,Low rolling resistance tires, winter tires and the rubber industry.
1. Process improvement: it helps to improve the quality of products.
2. The ultimate tensile strength: it can provide high tensile strength.
3. Wear resistance: It can improve wear resistance, enhance the ability to resist wear, and can improve the service life when used in the sole of sports shoes.
4. Stiffness: it can improve the hardness of the material, making it hard and strong.
5. Good winter performance: high dispersity silica can provide novel tread compound to ensure the winter performance of tires.
6. Wet traction: It can keep the tires in good grip on wet roads, so as to maintain good contact with the road.
7. Reduce rolling resistance: Improving traction on wet surfaces helps reduce tire wear.
