In late August, the domestic chemical sector continues to operate under the traditional summer off-season. Persistently high temperatures restrict the operating load of downstream manufacturers, and factories in many regions take the initiative to adjust production schedules to avoid safety risks caused by extreme heat. Upstream and downstream participants maintain a wait-and-see attitude, the overall trading pace of bulk chemicals slows down, large orders are scarce, and transactions mainly consist of short-term restocking for rigid demand. Against this backdrop, the precipitated silica industry shows obvious divergent market performance, with its development focus gradually shifting from capacity expansion to quality upgrading. Conventional precipitated silica suffers from weak demand in traditional downstream sectors including tires, general rubber and civil coatings, leading to low trading activity and narrow price fluctuations. Most manufacturers arrange production according to orders and flexibly control inventory to achieve stable operation. In contrast, functional products such as hydrophobically modified silica, high-dispersion silica and fumed silica enjoy sufficient order backlogs and firm quotations with little seasonal volatility, supported by continuous demand from emerging tracks such as new energy, high-end organosilicon, biomedicine and special composite materials. These products serve as the core segment underpinning industrial profitability. With the continuous upgrading of the downstream industrial chain, the old model relying solely on capacity expansion and price competition is no longer viable. Custom formula development, product performance optimization and supporting technical service capabilities have gradually become core factors for enterprises to capture market share.

　　From the perspective of upstream raw material costs, basic feedstocks for precipitated silica including sodium silicate, soda ash and sulfuric acid have generally faced downward pressure recently. The soda ash market features ample supply and rising social inventory. Demand recovery in downstream glass and detergent industries falls short of expectations, and prices fluctuate at low levels for a long time, offering little cost support for finished precipitated silica. The sulfuric acid market enters the traditional off-season alongside the fertilizer and metallurgy sectors, with shrinking demand and continuous softening of regional quotations. Falling prices of basic raw materials have reduced raw procurement costs for precipitated silica to some extent, easing profit pressure on small and medium-sized manufacturers. The cost logic of fumed silica is entirely different. Price fluctuations of upstream organosilicon monomers and high-purity silicon sources transmit sensitively. The whole preparation process consumes substantial energy, while investment in waste gas and wastewater treatment, powder purification and surface modification remains high, resulting in rigid production costs. Even if bulk raw material prices decline, the selling prices of high-end fumed silica and ultra-high-purity modified grades can hardly fall synchronously. The cost gap between different processes further consolidates the hierarchical market pattern of high-end and low-end products in the industry.

　　The supply side presents a structural feature of loose low-end supply and tight high-end supply. Leading domestic precipitated silica manufacturers maintain stable operating rates, adhere to the production-to-order model, and prudently arrange the launch of new capacity to avoid vicious price wars across the industry. A large number of small and medium-sized production lines focus on homogeneous general grades without independent modification R&D capabilities, resulting in highly substitutable products. To compete for existing market share, some suppliers accept orders at discounted prices, continuously curbing room for price increases of conventional precipitated silica. In the fumed silica segment, domestic leading enterprises keep optimizing production processes to improve powder purity, dispersibility and hydrophobic stability, steadily advancing import substitution. Nevertheless, special ultra-high-purity modified precipitated silica applied in semiconductor materials, lithium battery separator coatings, food additives, medical silicone and high-end optical materials features high production barriers, heavy investment in supporting equipment and long mass production cycles. Overall supply remains tight with a prolonged supply shortage, granting relevant manufacturers stronger pricing power and considerable profit margins.

　　The divergence of downstream consumption markets continues to deepen: demand weakens in traditional markets while emerging high-end application tracks keep expanding. In traditional fields such as tire manufacturing, ordinary rubber parts and basic civil coatings, downstream factories cut operating rates due to high temperatures. Procurement enterprises generally adopt just-in-time purchasing strategies with low willingness for large-scale stockpiling, directly dragging down demand for conventional precipitated silica. Emerging fields including lithium battery supporting materials, photovoltaic sealing silicone rubber, oral care abrasive fillers, food anti-caking additives, high-end printing inks, electronic packaging fillers and medical elastomer products maintain sound growth momentum. Downstream clients impose strict requirements on indicators of precipitated silica such as impurity content, specific surface area, dispersion uniformity, weather resistance and hydrophobic-lipophilic performance. The proportion of customized procurement rises year by year, continuously driving market demand for various functionally modified precipitated silica. Meanwhile, domestic policies for green tires are continuously rolled out, and energy consumption control standards for vehicle manufacturers keep tightening, forcing tire enterprises to optimize rubber formulas. This fuels steady growth in alternative demand for high-dispersion precipitated silica in the tire industry and points out a transformation direction for numerous precipitated silica producers.

　　Rules in the foreign trade market keep updating, and the structure of export products accelerates optimization and adjustment. The global green trade system is continuously improved, and overseas buyers carry out increasingly strict reviews on documents such as carbon footprint verification, low-carbon production certification, heavy metal limit testing and product safety compliance reports. Domestic manufacturers with green production qualifications, a complete full-process quality control system and supporting testing capabilities hold prominent advantages in international bidding and are more likely to secure long-term and stable overseas cooperation orders. Markets in Europe, America and Southeast Asia maintain steady procurement demand for special functional precipitated silica with favorable export profit margins. The export track for ordinary industrial precipitated silica sees fierce competition. Continuous expansion of local supporting capacity in Southeast Asia and prevalent bargaining by overseas purchasers keep squeezing export profits of low-end products. Market conditions force domestic enterprises to phase out backward and inefficient capacity, increase R&D expenditure, optimize the export product mix and raise the export proportion of high value-added functional precipitated silica. In addition, uncertain factors such as fluctuations in international ocean freight rates, adjustments to tariff policies of various countries and geopolitical trade frictions raise operational risks for foreign trade businesses in terms of order delivery, cost accounting and contract performance of precipitated silica.

　　Regarding the market outlook, in the short run, traditional downstream industries have not yet entered a recovery phase. Conventional precipitated silica is likely to maintain a weak consolidating trend, lacking sufficient momentum for sharp price rises or falls. Market movement is mainly governed by the game between supply and demand. In September, the chemical industry ushers in the traditional peak season known as "Golden September and Silver October". The operating rates of downstream industries including rubber products, coatings, inks and plastic processing are expected to gradually rebound. The concentrated release of downstream restocking demand may drive a month-on-month increase in overall market inquiries for precipitated silica and slightly improve trading sentiment. From a medium and long-term perspective, China’s dual-carbon control policies continue to be implemented, environmental supervision becomes normalized, and green low-carbon production processes, customized surface modification technologies and the development of high-purity functional products will serve as the core themes for the transformation and upgrading of the precipitated silica industry. Industrial capital, high-quality downstream orders and profits will keep concentrating on leading enterprises with independent R&D strength and complete supporting technical services, and the profit gap between high-end and low-end products may widen further. Future industrial competition will no longer be limited to comparisons of production capacity scale. R&D of powder modification formulas, refined surface treatment processes, full-process quality control and integrated technical supporting services will jointly determine enterprises’ long-term market position and industry discourse power.
