3. Typical application scenarios


Tire manufacturing

Green tires: replace part of carbon black, reduce rolling resistance by 30%, and improve fuel efficiency.

Tread tear resistance: enhance cutting/tearing performance and extend service life.


Seals and hoses

Improve the fluidity of rubber, reduce mold wear, and improve the surface finish of products.


Special rubber products

In hydrogenated nitrile rubber (HNBR), modified silica can improve heat resistance (reduced storage modulus at 100°C) and compression deformation resistance.


4. Market trends


Environmental drive

With the advancement of the EU tire labeling law and my country's "green tire" policy, the demand for highly dispersed silica is expected to grow by more than 8% annually.


Technology upgrade

Surface modification technology (such as mercaptosilane coupling agent) further improves the reinforcement effect and expands its application in high-end rubber products.


Alternative space

Traditional anti-blocking agents (such as oleic acid amide) have the risk of migration and precipitation, and the long-term stability of silica has gradually made it a mainstream choice.
