Highly dispersion precipitated silica Application

Highly dispersion precipitated Silica usede in  green tires,Low rolling resistance tires, winter tires and the rubber industry.

• Process improvement: it helps to improve the quality of products.
• The ultimate tensile strength: it can provide high tensile strength.
• 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.
• Stiffness: it can improve the hardness of the material, making it hard and strong.
• Good winter performance: high dispersity silica can provide novel tread compound to ensure the winter performance of tires.
• Wet traction: It can keep the tires in good grip on wet roads, so as to maintain good contact with the road.
• Reduce rolling resistance: Improving traction on wet surfaces helps reduce tire wear.
