Entering mid-August, China's white carbon black industry has officially emerged from the sluggish off-season caused by high temperatures in July. Downstream manufacturers across various sectors have steadily resumed production, bringing phased adjustments to the overall supply and demand landscape. According to monitoring data from multiple institutions including Business Society, China Chemical Online and the Organosilicon Industrial Chain Research Center, the mainstream average price of general rubber-grade precipitated white carbon black nationwide stood at 5,966.67 RMB / ton on August 10, representing a slight increase of 33.34 RMB / ton or 0.56% compared with the price of 5,933.33 RMB / ton on August 1. Spot prices remained stable throughout the day without drastic fluctuations. At present, the industry presents obvious polarization: low-end generic precipitated white carbon black suffers from oversupply with limited room for price hikes; high-dispersion tire-specific white carbon black, food and pharmaceutical-grade ultra-fine white carbon black, as well as hydrophilic and hydrophobic modified fumed white carbon black see robust demand and tight supply, which firmly underpin prices. Market trends are jointly affected by raw material costs, downstream application demand, export orders and energy consumption policies.

　　Precipitated white carbon black accounts for the largest proportion of the market, and its price fluctuations directly reflect the prosperity of the whole industry. Affected by nationwide extreme high temperatures in July, the operating rates of factories engaged in tire manufacturing, rubber sealing parts, conveyor belts, plastic shoe soles, industrial anti-corrosion coatings and other traditional downstream businesses kept declining. Most manufacturers cut production loads and consumed existing inventories, leading to scarce market inquiries and dull trading sentiment. With temperatures dropping in August and improved production conditions nationwide, major domestic tire enterprises and small and medium-sized rubber product factories have resumed full-capacity production, triggering concentrated restocking demand. The spot trading volume has increased by more than 20% compared with the same period last month. Nevertheless, the long-standing industrial overcapacity problem has not been fundamentally resolved. Numerous small and medium-sized precipitated white carbon black manufacturers have released concentrated production capacity, pushing the inventories of standard generic white carbon black to an annual high. Merchants cut prices to withdraw funds, intensifying competition in the low-end market. As a result, basic products can only achieve modest tentative price increases rather than a sharp upturn. Price gaps among segmented products keep expanding: conventional loose precipitated white carbon black is mainly quoted at 5,600 to 5,800 RMB / ton; spherical anti-settling grades are priced between 5,850 and 6,100 RMB / ton; high-dispersion reinforcing grades tailored for low rolling resistance new energy vehicle tires are in tight supply, with mainstream transaction prices stably ranging from 6,300 to 6,700 RMB / ton. Ultra-fine high-purity white carbon black used as food anticaking agents and pharmaceutical excipients boasts rigid demand. Steady purchases from daily chemical and health product enterprises keep its price firmly between 6,400 and 6,800 RMB / ton with trivial fluctuations.

　　Export trade provides strong support for the market of precipitated white carbon black. Steady infrastructure construction in Southeast Asia, the Middle East and Latin America has created large capacity gaps for local rubber products and architectural coatings, driving rising procurement orders for Chinese white carbon black. With outstanding cost performance, domestic high-dispersion tire-grade white carbon black has gradually seized market share previously occupied by well-established European and American brands, advancing both import substitution and outbound exports. Customs statistics reveal that China's total export volume of white carbon black rose by 12.7% month-on-month in the past month. Robust overseas orders have effectively alleviated the domestic backlog of low-end products and provided a bottom support for domestic spot prices.

　　Market polarization is more prominent in the fumed white carbon black sector, whose operation is mainly determined by raw material costs and demand from emerging industries. Methyltrichlorosilane, the core raw material for fumed white carbon black located in the upper reaches of the organosilicon industrial chain, has seen tightened supply due to seasonal energy consumption control and staggered production policies implemented in many regions this summer. Restricted operating rates of organosilicon monomer manufacturers have moderately lifted procurement costs, delivering mild upward momentum to fumed white carbon black prices from the cost side. In terms of demand, traditional application fields remain sluggish. Purchasing activity for architectural sealants, ordinary silicone rubber and general plastic reinforcement is slow, dominated by small batch urgent replenishment orders. In contrast, demand from new energy, optoelectronics and high-end electronics sectors has surged sharply. Hydrophilic fumed white carbon black is widely applied in photovoltaic encapsulant adhesives, lithium battery separator coatings and electronic potting adhesives; hydrophobic modified fumed white carbon black is adopted in high-end liquid silicone rubber, thermal conductive gaskets, cosmetics, precision instrument moisture-proof fillers and more. Leading downstream enterprises have locked in supplies through long-term contracts, resulting in tight availability of high-end products, extended order cycles and steadily climbing prices. By contrast, demand for mid-to-low end general fumed white carbon black remains weak. Manufacturers stick to on-demand production and inventory digestion. Currently, the overall average operating rate of China’s fumed white carbon black industry stands at around 65%, with enterprises actively adjusting output to avoid losses caused by low prices.

　　In terms of industrial policies and technological innovation, low-carbon and green transformation has become the mainstream development trend of the white carbon black industry. As global carbon tariffs and low-carbon trade regulations are gradually implemented, many leading domestic enterprises have launched innovative low-carbon circular production technologies. Silica raw materials extracted from renewable waste including rice husk ash, industrial waste silica sand and organosilicon byproducts are adopted to produce white carbon black. This method drastically cuts fossil fuel consumption, reduces product carbon footprints, meets overseas low-carbon procurement standards and further boosts the international competitiveness of domestic white carbon black. Meanwhile, the industry is optimizing its capacity structure: outdated, high-energy-consuming production lines for low-quality generic products are being phased out, while resources are concentrated on researching and manufacturing high-end special products such as lithium battery coating-specific white carbon black, optical-grade transparent fillers, pharmaceutical high-purity silica and aerogel composite modified white carbon black, breaking away from the long-term vicious competition driven by low-end homogenization and price wars. Many enterprises have strengthened university-industry-research cooperation to conduct graft modification on the surface of white carbon black, improving its dispersibility and compatibility in various substrates and expanding downstream application scenarios.

　　Looking ahead to the market outlook, professional chemical analysts have made predictions based on comprehensive supply and demand conditions: In mid-to-late August, demand from the domestic traditional rubber and coating industries will be fully unleashed, coupled with concentrated pre-Mid-Autumn Festival stocking by downstream manufacturers. Prices of high-dispersion precipitated white carbon black, hydrophilic & hydrophobic modified fumed white carbon black, as well as food and pharmaceutical-grade high-purity white carbon black are expected to rise further. Restrained by sufficient inventories, generic standard precipitated white carbon black will likely maintain narrow sideways fluctuations at low levels. Three factors require close attention going forward: adjustments to energy consumption control policies, price volatility of upstream organosilicon raw materials and fluctuations in overseas export orders. Overall, the white carbon black industry has entered a long-term structural development stage featuring "strong high-end market and pressured low-end market", with the new energy and advanced new materials sectors continuing to serve as the core growth drivers of the industry.
