(August 11, 2026)On August 11, 2026, China’s white carbon black market entered a stable operating phase in mid-August. Following sluggish demand and dull trading throughout the off-season in July, downstream end customers have embarked on gradual pre-peak stockpiling. The volume of market inquiries and spot transactions has risen steadily. Upstream raw materials including soda ash, water glass, sulfuric acid and organosilicon monomers have climbed moderately, continuously forming a solid cost floor for the industry. The traditional rubber goods sector is gearing up for its peak sales season, while demand keeps expanding in emerging fields such as photovoltaic encapsulation, energy storage electronic components and supporting materials for new energy vehicle tires. Combined positive factors have lifted the overall white carbon black market slightly. Nevertheless, long-standing structural industrial contradictions remain unresolved. Conventional precipitated silica is plagued by severe overcapacity and inventory backlogs, posing strong resistance to price hikes. In contrast, supplies of modified functional silica tailored for green tires, electronic sealing and premium daily chemical applications have tightened, with endless domestic and overseas orders pouring in, further widening price gaps across product grades and regions.
In terms of spot quotations, regional and tiered price disparities have grown more pronounced this week. Data monitored by chemical big data platforms shows the national average price of precipitated silica edged upward modestly. As China’s core production, sales and distribution hub, East China offers tax-inclusive ex-factory prices ranging from 6,080 to 6,420 yuan per ton for high-dispersion precipitated silica specially formulated for new energy passenger car tires. In northern and southern production zones including Shandong, Hebei, northern Jiangsu and Fujian, conventional industrial filler-grade precipitated silica faces pronounced sales pressure, with mainstream spot transaction prices fixed between 5,330 and 5,890 yuan per ton. Weak demand has kept low-end general filler silica lingering at rock-bottom levels, with the average market price below 2,800 yuan per ton. High-purity specialty silica used for food anticaking agents and pharmaceutical carriers maintains firm pricing above 6,720 yuan per ton, backed by stringent production thresholds and stable rigid demand. Benefiting from tightened upstream organosilicon supply, the fumed silica market stays consistently strong. Domestic general hydrophilic fumed silica is quoted at 20,500–24,100 yuan per ton, while premium hydrophobically modified grades hold steady at 26,000–29,200 yuan per ton. Imported high-end hydrophobic fumed silica suffers from acute spot shortages; order delivery times have generally been postponed until late September, with quotations ranging from 29,800 to 39,800 yuan per ton.
Sustained cost support firmly underpins the market price bottom. Soda ash, the core feedstock for precipitated silica production, has entered its annual concentrated maintenance cycle. Multiple domestic soda ash production lines have been shut down for overhaul, reducing market supply and pushing spot prices roughly 520 yuan per ton higher month-on-month. Sulfuric acid prices rose slightly on rebounding operating rates in downstream fertilizer and metallurgical industries alongside scheduled plant maintenance. Stable prices of industrial silicon and methylchlorosilanes have directly lifted overall processing costs for fumed silica. Meanwhile, China’s energy conservation, environmental protection and dual energy consumption controls have become increasingly stringent. Mandatory assessment standards covering wastewater resource recycling, comprehensive utilization of by-product sodium sulfate and energy consumption quotas per unit product have been fully enforced. A large number of small and medium-sized manufacturers equipped with outdated technology, inadequate environmental compliance and excessive energy consumption have been forced to cut production, suspend operations or exit the industry entirely. Industrial capacity resources are continuously concentrating among leading enterprises, effectively curbing chaotic vicious low-price competition.
Downstream demand operates in a dual-cycle pattern: recovery in traditional industries and robust growth in emerging sectors. The tire and rubber industry remains the largest consumption market for white carbon black. As the traditional autumn and winter sales season draws near, major domestic tire manufacturers have successively raised production line operating loads. Formulations for new energy vehicle tires are continuously optimized and upgraded, lifting the proportion of high-dispersion silica year after year. Capable of lowering tire rolling resistance, extending electric vehicle driving range, enhancing road grip on rainy and snowy surfaces and prolonging tire service life, this grade boasts full order backlogs and thriving production and sales. Manufacturers of rubber hoses, sealing gaskets, rubber shoe soles, conveyor belts and other traditional rubber and plastic products only conduct small-scale replenishment on demand, without large-scale centralized stockpiling.
Demand from waterborne coatings, home renovation and outdoor building protection sectors has been steadily released. The outreach of eco-friendly waterborne coatings keeps expanding, driving steady growth in demand for white carbon black as a rheology regulator, matting agent and pigment anti-settling additive. With the arrival of autumn, urban exterior wall renovation, stone maintenance, concrete waterproofing and anti-seepage projects for bridges and underground garages kick off intensively, broadening application scenarios for hydrophobic silica compounded with silane systems. Silicone sealants for photovoltaic module encapsulation, potting adhesives for energy storage battery modules and insulating silicone rubber for electronic components have emerged as new growth engines. Steady growth in China’s newly installed photovoltaic capacity has boosted the silicone rubber industry, pushing the year-on-year consumption growth rate of white carbon black in this segment above 15%. Custom trial orders and bulk procurement requests for ultra-fine modified precipitated silica and hydrophobic fumed silica keep flowing in. In addition, steady demand growth in fine chemical segments including pesticide sustained-release carriers, thickeners for skincare daily chemicals and feed anticaking agents continues to expand the application scope of white carbon black.
Production scheduling strategies vary drastically among suppliers. The precipitated silica sector boasts enormous overall capacity, and inventories of low-end generic products remain excessively high. To avoid unsold stockpiles, small and medium-sized factories keep operating rates between 75% and 82%, strictly adopting a produce-to-order model and cutting output of low-end filler products. Leading enterprises have proactively adjusted product portfolios by slashing capacity for low-priced generic grades and ramping up production of functional silica including tire-specific high-dispersion, hydrophobically modified and ultra-fine nano varieties, which effectively digests inventories and lifts overall profitability. Restrained by insufficient upstream organosilicon monomer supply, the overall operating rate of the fumed silica sector remains low at 66%–69%, with limited total spot inventories and strong resistance against price declines. Exports maintain robust momentum. Steady demand for infrastructure and construction materials in Southeast Asia, green tires in Europe and daily rubber and plastic processing goods in Latin America has continuously lifted the global reputation of high-performance Chinese white carbon black, generating ample overseas orders that effectively ease fierce internal competition in the domestic low-end market and serve as a core driver boosting industrial revenue growth.
The industry is speeding up green low-carbon transformation and high-end technological research and development. Domestic new material enterprises keep making breakthroughs in core production techniques for high-dispersion silica, bringing key performance indicators such as reinforcing effect, weather resistance, anti-aging property, wear resistance and tear resistance gradually in line with top international brands and accelerating import substitution for high-end products. Widespread adoption of recycled production wastewater and recovered by-product sodium sulfate reduces pollutant emissions while lowering corporate production and operational costs. Globally, major overseas chemical conglomerates continue expanding white carbon black capacity in North America to support green tire manufacturing. This opens up more overseas space for Chinese white carbon black exporters yet intensifies international competition concurrently.
Based on comprehensive assessments from multiple chemical industry research institutions: the traditional peak consumption season will fully unfold from late August to early September. Tire and rubber goods manufacturers will markedly increase stockpiling efforts, and stable upstream raw material costs will provide solid support, leaving room for a mild uptick across the entire white carbon black market. However, excess capacity of conventional precipitated silica cannot be digested in the short term, ruling out drastic price hikes; prices will generally trend slightly upward amid fluctuations. High-dispersion tire-specific silica, hydrophobic fumed silica and new energy-oriented modified silica will remain in tight supply, with far stronger price gains than ordinary industrial-grade varieties. In the long run, phasing out backward low-end capacity, deepening R&D into functional modification technologies, capturing dividends from the new energy industry and steadily expanding overseas export channels constitute the only path for China’s white carbon black industry to escape vicious low-price competition and achieve green, high-end, high-quality and sustainable development.
