White Carbon Black Industry Pattern: Global Competition and China's Breakthrough
Market Distribution:
Concentrated production capacity: The top 10 global manufacturers (such as Eckman, Total, Corning, etc.) account for 65% of the market share, while China's production capacity accounts for 30%, but high-end products rely on imports.
Price differentiation: The average price of gas-phase white carbon black is 20000 yuan/ton, the precipitation method product is 4000 yuan/ton, and the gross profit margin in the high-end field reaches 50%.
technology barrier:
Gas phase method patent: Germany's Innolux holds a core patent for silicon tetrachloride hydrolysis, which limits the development of Chinese enterprises in the high-end electronic packaging field.
Modification technology: Shin Etsu Chemical of Japan has developed fluorosilicon modified white carbon black, which is irreplaceable in 5G base station heat dissipation materials.
China's breakthrough:
Non metallic mineral source: Koning Chemical uses kaolin to prepare white carbon black, reducing costs by 40% and achieving a product purity of 98%.
New energy demand: By 2025, China's demand for white carbon black for lithium batteries will reach 150000 tons, with a 30% expansion in gas-phase production capacity driven by this method.
Future trends:
Green preparation: The technology for preparing white carbon black from biomass silicon source (rice husk ash) is mature, and carbon emissions are reduced by 60% compared to traditional processes.
Functional composite: White carbon black/graphene composite materials have great potential in the field of flexible electronics, with a tensile modulus of up to 50GPa.
