Rubber industry: the "low-carbon cornerstone" of green tires
As a traditional application field of white carbon black, the rubber industry remains its largest consumer market, accounting for 62%. In tire manufacturing, highly dispersed white carbon black can help fuel vehicles save 5% -8% fuel and increase electric vehicle range by 8% -10% by reducing rolling resistance. The "ultra-low rolling resistance formula" jointly developed by Quecheng Group and Michelin increases the amount of white carbon black added to each tire from 500 grams to 800 grams, combined with silane coupling agent, to achieve the EU A-level standard for tire anti-skid performance, while reducing rolling resistance by 22%. At present, this technology has been applied to Tesla Model 3, BYD Han and other models, reducing carbon dioxide emissions by more than 1 ton per vehicle per year.


In industrial rubber products such as seals and conveyor belts, white carbon black significantly extends product life by enhancing wear resistance and high temperature resistance. For example, the "oil resistant white carbon black" developed by Black Cat Corporation can extend the service life of automotive transmission belts from 3 years to 6 years, reducing the resource consumption caused by replacement frequency.


New energy field: "performance enhancer" for batteries and photovoltaics
In the field of lithium-ion batteries, white carbon black is becoming a key material for improving energy density. CATL has increased the energy density of batteries to 400Wh/kg and achieved a range of over 1000 kilometers by combining nanoscale white carbon black with silicon carbon composite negative electrodes; As a positive electrode material conductive agent, it can improve the low-temperature performance of lithium iron phosphate batteries by 15%, solving the problem of electric vehicle range degradation in winter. In addition, the "porous white carbon black" developed by Yuanxiang New Materials serves as a separator coating in sodium ion batteries, increasing ion conductivity by 30% and achieving a cycle life of over 5000 times, providing a low-cost solution for the energy storage market.


In the field of photovoltaics, white carbon black as a film additive can enhance the anti PID (potential induced decay) performance of components. Experimental data from Zhonglai Corporation shows that adding 2% white carbon black to EVA film can reduce the 25 year power attenuation rate of photovoltaic modules from 8% to 3%, significantly extending their service life.


Biopharmaceuticals: "Nanocarriers" for Targeted Therapy
The nanoscale pore structure and surface modifiability of white carbon black make it an ideal carrier for drug delivery. The "aminated white carbon black" jointly developed by the Institute of Process Engineering of the Chinese Academy of Sciences and Yuanxiang New Material can load the chemotherapy drug doxorubicin, reducing the tumor volume by 82% in the breast cancer model, while reducing the damage to normal tissues. At present, the technology has entered phase II clinical trials and is expected to be launched in 2027. In addition, white carbon black can also be used as orthopedic repair materials, and its loaded antibiotics can be continuously released within 60 days, increasing the cure rate of bone infections from 70% to 95%.


industry outlook
Market research firm QYResearch predicts that from 2025 to 2030, the global market size of white carbon black in the fields of new energy and biomedicine will grow at an average annual rate of 25%, and its proportion will exceed 50% by 2030. Chinese companies are expected to increase their market share in the high-end market from the current 28% to 45%, becoming the dominant players in global technology standards.
