Technological Breakthrough: From "Reinforcing Agents" to "Low Carbon Solutions"
Precipitation method white carbon black (chemical formula SiO ₂ · nH ₂ O) is generated by the reaction of sodium silicate and sulfuric acid. Its porous structure and high specific surface area (100-300m ²/g) can significantly reduce tire rolling resistance. The "highly dispersed white carbon black" developed by Quecheng Group uses surface hydroxyl modification technology to reduce the particle aggregation index from 3.2 to 1.5, increasing the tire's wet skid resistance index by 15% and reducing rolling resistance by 20%, meeting the A-level standard of the EU labeling method. The company's Thailand base adopts a bio based process of replacing quartz sand with rice husk ash, reducing the carbon footprint of a single ton of product by 40%. It has entered the supply chain systems of Bridgestone and Michelin.


Market pattern: China leads the world in production capacity, key to breaking through the high-end trend
China's production capacity of precipitated white carbon black accounts for 58% of the global total, but the self-sufficiency rate of high-end products (such as highly dispersed white carbon black) is less than 40%. Shandong Lianke Technology has improved the particle size uniformity of its products to 99.5% through the integrated device of "high gravity reaction spray drying", breaking the foreign monopoly on 5-nanometer chip packaging materials; However, the "medical white carbon black" developed by Yuanxiang New Material has achieved targeted drug delivery through amination modification, which has increased the tumor inhibition rate to 82% in the breast cancer model. Relevant technologies have entered the phase III clinical trial.
