(August 10, 2026)By late early August, intense heat has gradually faded across China, production conditions for downstream manufacturing sectors including rubber, coatings and construction materials have improved steadily, and the white carbon black market has officially emerged from the sluggish off-season in July with trading sentiment warming continuously. Based on industrial chain monitoring data from major chemical information platforms, the average transaction price of mainstream rubber-grade precipitated white carbon black edged upward nationwide on August 10. The overall market is marked by recovering rigid demand, inventory divergence and intensified game between upstream and downstream sectors. The performance gap between precipitated and fumed white carbon black keeps widening, while high-end fillers for new energy applications remain strong.

　　Precipitated white carbon black accounts for the vast majority of China’s white carbon black market, and its price fluctuations directly reflect the overall industrial trend. Affected by persistent scorching heat in July, factories nationwide cut operating rates due to temperature limits and power shortages. Tire plants, rubber component manufacturers, conveyor belt producers, industrial anti-corrosion coating factories and plastic goods makers all scaled back production plans, only placing small orders for replenishment as needed. Market inquiries were scarce and spot trading stayed sluggish. Most traders were burdened by inventory backlogs and tight capital turnover. As temperatures dropped in August, terminal downstream enterprises resumed full-capacity operation one after another. Coupled with expectations of pre-stocking ahead of the traditional busy September season, purchasing demand across the rubber industrial chain surged collectively, pushing spot transaction volume up by over 20% month-on-month recently. Nevertheless, the long-standing problem of excessive low-end capacity has not been resolved. Massive stocks of standard-grade white carbon black have piled up at numerous small and medium manufacturers. Merchants cut prices to accelerate capital recovery, curbing the upside for conventional products which only saw mild tentative hikes. Price gaps between segmented products continue to expand: regular loose precipitated white carbon black sells steadily with mainstream factory prices ranging from 5,600 to 5,800 RMB / ton; anti-settling microsphere grades tailored for coating systems are stably quoted at 5,850 to 6,100 RMB / ton; high-reinforcement, high-dispersion white carbon black designed for low rolling resistance new energy vehicle tires faces tight supply. Leading tire companies place long-term locked orders, keeping transaction prices firm between 6,300 and 6,700 RMB / ton. Ultra-fine high-purity white carbon black used as food anti-caking agents and pharmaceutical excipients enjoys year-round stable demand barely affected by seasonal swings, maintaining solid prices of 6,400 to 6,800 RMB / ton.

　　Overseas export trade serves as a vital anchor stabilizing the precipitated white carbon black market. Steady delivery of infrastructure projects across Southeast Asia, the Middle East and Latin America has created large capacity shortages for local rubber processing and architectural coatings, driving rising procurement orders for Chinese white carbon black. Boasting prominent cost performance, domestic high-end tire-grade white carbon black has steadily captured market share once dominated by time-honored European and American chemical enterprises, advancing both import substitution and outbound exports simultaneously. China’s total white carbon black export volume rose 12.7% month-on-month over the past month. Large overseas orders have effectively digested excess low-end domestic inventory, relieved sales pressure in the home market and underpinned spot prices.

　　Structural polarization is far more striking in the fumed white carbon black market, jointly dominated by upstream raw material costs and demand from emerging sectors. Methyltrichlorosilane, the core feedstock for fumed white carbon black in the upper reaches of the organosilicon chain, saw tightened supply this summer. Multiple regions implemented staggered production and energy consumption control policies, restricting operating rates of organosilicon monomer plants and pushing up raw material procurement costs moderately, delivering mild upward support to fumed white carbon black prices from the cost side. Demand varies drastically across segments: traditional fields remain tepid. Purchasing for construction sealants, general silicone rubber and plastic reinforcement proceeds slowly, consisting mostly of scattered small replenishment orders. In contrast, demand from new energy and fine chemical sectors such as photovoltaic encapsulant adhesives, lithium battery separator coatings, electronic potting compounds, premium liquid silicone rubber, thermal conductive gaskets and cosmetic raw materials keeps expanding. Hydrophilic and hydrophobic modified high-end fumed white carbon black is in short supply, leading to extended order cycles and steadily firm prices at manufacturers. Conversely, mid-to-low grade general fumed white carbon black suffers from weak demand. Factories arrange production on demand to clear inventories. Currently, the overall operating rate of China’s fumed white carbon black industry hovers around 65%, as enterprises deliberately trim output to avoid losses amid low prices.

　　Green low-carbon transformation and high-end product upgrading have become irreversible trends for the white carbon black industry. With the global carbon tariff system officially launched and overseas low-carbon procurement standards growing stricter, leading domestic white carbon black enterprises have successively rolled out circular low-carbon production processes. Silica extracted from renewable waste including rice husk ash, industrial waste silica residue and organosilicon byproducts is adopted to produce white carbon black. This approach drastically reduces fossil fuel consumption and carbon emissions, complies with overseas low-carbon export requirements and greatly boosts the international competitiveness of domestic products. Meanwhile, the industry is phasing out outdated high-energy-consuming, low-quality production lines, cutting homogeneous low-end capacity and concentrating resources on developing specialty new materials such as white carbon black dedicated to lithium battery coatings, optical high-transparency fillers, pharmaceutical high-purity silica and aerogel composite modified white carbon black, breaking free from the predicament of vicious price competition driven by homogenization. Many enterprises have deepened university-industry-research collaboration to conduct surface graft modification on white carbon black, improving powder dispersibility and substrate compatibility to continuously expand application scenarios.

　　Chemical research institutions offered forecasts on the future market trend: In mid-to-late August, demand from the downstream rubber and coating industries will be fully unleashed, together with the pre-Mid-Autumn Festival stocking boom. Prices of high-dispersion precipitated white carbon black, modified fumed white carbon black and food & pharmaceutical-grade high-purity white carbon black will still have room to climb. Restrained by ample inventories, conventional standard precipitated white carbon black will continue narrow sideways fluctuations at low levels. Three key factors deserve ongoing attention: adjustments to energy consumption control policies, price volatility of upstream organosilicon raw materials and changes in overseas export orders. In the long run, the white carbon black industry has entered a new structural development phase where high-end products surge while low-end varieties face downward pressure. New energy and premium advanced materials will remain the core growth drivers of the sector for a long time to come.
