White carbon black, mainly divided into gas-phase white carbon black and precipitation white carbon black, is widely used in multiple industries due to its high specific surface area, excellent reinforcement performance, and chemical stability
Key additives for green tires
In the manufacturing of "green tires", white carbon black can replace some carbon black, reduce tire rolling resistance, improve fuel efficiency, and reduce carbon emissions. The EU's "labeling law" and other regulations are driving the continuous growth of the penetration rate of white carbon black in the tire industry.
Core reinforcement material of silicone rubber
White carbon black can significantly improve the mechanical properties and aging resistance of high-temperature vulcanized silicone rubber (HTV) and room temperature vulcanized silicone rubber (RTV), and is widely used in fields such as electronic packaging and medical devices.
Rheological modifiers for coatings and inks
White carbon black can improve the anti settling and anti sagging performance of coatings, and enhance wear resistance, becoming an important additive for high-end industrial coatings.
Safe selection of personal care products
White carbon black, as a mild friction and thickening agent in toothpaste and cosmetics, meets safety standards such as FDA, and the market demand is steadily increasing.
2、 Technological innovation: parallel high-end and green production
Breakthrough in Preparation Technology of Nanoscale White Carbon Black
In recent years, domestic enterprises such as Hesheng Silicon Industry and Jiyao Holdings have successfully mass produced high-purity nano white carbon black by improving the gas-phase process, breaking the technological monopoly of foreign enterprises such as Yingchuang and Cabot.
Promotion of environmentally friendly precipitation process
The traditional precipitation method has high energy consumption and large wastewater discharge, while the newly developed "green precipitation method" significantly reduces environmental impact by recycling by-products (such as sodium sulfate), which is in line with the "dual carbon" goal.
Surface modification technology enhances application performance
By modifying with silane coupling agents, the compatibility between white carbon black and organic materials is enhanced, further expanding its applications in emerging fields such as composite materials and new energy batteries.
3、 Market pattern: Asian production capacity expansion, high-end dependence on imports
China becomes the world's largest producer
In 2023, China's white carbon black production capacity will account for over 40% of the world's total, with major enterprises including Fujian Yuanxiang New Materials and Shandong Lianke Technology. However, high-end products still rely on imports.
International giants accelerate their layout
Evonik, a German company, announced the expansion of its gas-phase white carbon black production capacity in Singapore to meet the demand of the electric vehicle and semiconductor industries in the Asia Pacific region.
Price fluctuations and raw material challenges
The price of silicon sources (such as silicon tetrachloride and sodium silicate) is greatly affected by energy costs, and companies are exploring alternative solutions such as biomass silicon sources to stabilize the supply chain.
4、 Future outlook: New energy and sustainable development become key driving forces
New energy vehicles drive demand
Progress has been made in the application research of white carbon black in silicon carbon negative electrode materials, which is expected to improve the energy density of lithium batteries.
New roles in biodegradable materials
White carbon black can improve mechanical properties and promote the development of environmentally friendly packaging industry in bioplastics such as PLA (polylactic acid).
Policy support and improvement of industry standards
The "14th Five Year Plan" for the development of China's new materials industry focuses on functional silicon materials, and the white carbon black industry is expected to usher in a new round of technological upgrades.
