On July 15, 2025, Beijing - From water pollution control in the Yangtze River Basin to semiconductor chip packaging, from medical dressings to high-end coatings, white carbon black is becoming a key material for solving resource constraints and industrial upgrading problems with its dual advantages of "environmental protection+high performance". According to data from the Ministry of Ecology and Environment, the application of white carbon black in the field of environmental governance in China will reach 120000 tons by 2025, an increase of 300% compared to 2020. The proportion of high-end manufacturing will exceed 40%, driving the industry's profit margin from 8% to 15%.


Environmental Governance: "Nano Sponge" for Sewage Treatment
The adsorption capacity of white carbon black for heavy metal ions and organic pollutants makes it a "star material" in the field of water treatment. In a sewage treatment project in a chemical industrial park in the Yangtze River Basin, the "modified white carbon black" developed by Lianke Technology has an adsorption capacity of 200mg/g for lead and cadmium ions, which is five times that of traditional activated carbon; Its photocatalytic degradation efficiency increases the COD (chemical oxygen demand) removal rate to 95% and reduces treatment costs by 60%. In addition, white carbon black can also be used for soil remediation, as the microorganisms it carries can degrade petroleum hydrocarbon pollutants, reducing the time for contaminated soil to restore its tillage ability from 10 years to 3 years.


In the field of air purification, the "honeycomb shaped white carbon black filter" developed by Black Cat Co., Ltd. has a filtration efficiency of 99.97% for PM2.5, and can also adsorb volatile organic compounds such as formaldehyde and benzene. It has been applied in air purification systems in public places such as hospitals and subways.


High end manufacturing: the "material cornerstone" of semiconductors and aerospace
In the semiconductor industry, white carbon black is a key material for chip packaging. The "high-purity white carbon black" developed by Jin Sanjiang has a purity of 99.999%, which can meet the requirements of the 5-nanometer chip process. As a reinforcing agent for epoxy plastic sealant, it can increase the thermal expansion coefficient of the chip to 98% of the substrate matching degree, reducing the risk of cracking caused by thermal stress. At present, the product has entered the supply chain systems of TSMC and Intel, breaking the foreign monopoly.


In the aerospace field, white carbon black becomes the core component of rocket engine nozzles and aircraft brake pads by enhancing the high temperature resistance and strength of composite materials. Experiments conducted by the AVIC Composite Materials Research Center have shown that adding 15% white carbon black to carbon fiber composite materials increases their temperature resistance from 350 ℃ to 600 ℃ and strength by 40%, which can meet the extreme environmental requirements of the new generation of spacecraft.


Daily Chemicals and Coatings: Empowerors of Green Living
In the field of daily chemical products, white carbon black, as a thickener and friction agent for toothpaste, can increase the stability of toothpaste by 30% while reducing the wear on enamel. Yunnan Baiyao's latest "Nano White Carbon Black Toothpaste" achieves a balance between cleanliness and mildness by controlling particle size between 50-100 nanometers, with sales exceeding 200 million yuan within three months of its launch.


In the coatings industry, white carbon black can replace titanium dioxide to achieve "reducing whiteness and increasing transparency". The "high transparency white carbon black coating" developed by Nippon Paint has increased the light transmittance of building glass from 85% to 92%, while improving insulation performance by 20%, which can reduce air conditioning energy consumption by 15%. In addition, white carbon black can also be used in automotive coatings, with its matte effect and scratch resistance, reducing the coating cost of high-end car models by 30%.


Policy and Market
China's 14th Five Year Plan clearly lists white carbon black as a strategic emerging industry material and provides tax exemptions and financial support for high-end product research and development. It is expected that by 2030, China will form three white carbon black industry clusters with an annual output value exceeding 5 billion yuan, and the global market share will exceed 45%, becoming the core force for global technology output and industrial upgrading.
