China’s domestic chemical market remains in the traditional summer off-season. Persistent high temperatures prevent midstream and downstream enterprises from operating at full capacity. The overall market sentiment stays cautious, with prices of most chemical raw materials fluctuating within a narrow range and lacking drivers for unilateral market moves. Against this backdrop, the silica industry continues its years-long structural differentiation. General precipitated silica is trapped in severe overcapacity, with sluggish recovery of traditional downstream demand and high inventory weighing down quotations. Transactions mainly consist of small orders for rigid demand. In contrast, functionally modified silica featuring specific reinforcement, matting, hydrophobicity and low impurity properties sees steadily rising market demand thanks to the expansion of new material industries and quality upgrades of end products. Leading manufacturers hold sufficient orders with tight spot supply and growing product bargaining power. The industry focus further shifts toward high value-added functional materials.

　　On the supply side, major domestic silica production lines have maintained high operating rates following previous maintenance and environmental rectification. Total industrial supply is adequate to meet market demand for basic fillers. However, the imbalance in product structure remains prominent. Massive capacity of general precipitated silica commissioned in previous years has been released, resulting in oversupply in the low-end market. Many small and medium-sized factories sell goods at low prices to keep production lines running, continuously dragging down transaction prices and squeezing industrial profit margins. Some long-loss small-scale production lines face shutdown and exit. For functionally modified silica, powder surface modification requires higher standards for equipment, formulation technology and quality control systems. New capacity takes a long time to launch and cannot expand rapidly in the short term. Dedicated modified production lines of leading enterprises are mostly pre-booked for long-term clients, leaving limited tradable spot goods and low inventory. Quotations stay stable and firm, and manufacturers generally avoid price competition in the low-end market. Meanwhile, many leading enterprises have built supporting R&D laboratories to customize modification solutions for different customer scenarios, further building technical barriers and widening the gap with small and medium competitors.

　　In terms of upstream raw materials and costs, prices of sodium silicate, sulfuric acid, various surface modification additives, steam and industrial electricity have fluctuated mildly recently. Overall production costs see little change and exert limited impact on silica market trends. Competition in the industry no longer simply relies on raw material procurement costs, but shifts toward comprehensive strengths including modification technology, batch stability, supporting testing services and carbon footprint management. Large enterprises with closed-loop circular production processes and low-carbon emission lines can control comprehensive production costs. Their products also meet relevant EU Carbon Border Adjustment Mechanism requirements and gain extra premiums in export markets. Small and medium-sized manufacturers using outdated processes with insufficient environmental supporting facilities face rising investment in environmental governance and stricter energy consumption control, shrinking their living space and accelerating the phase-out of backward capacity.

　　Downstream segmented markets show obvious divergence between hot and sluggish segments. Traditional fields such as ordinary rubber parts, general civil coatings, feed additives and basic daily chemical fillers face flat end-market demand. Downstream finished product manufacturers receive insufficient orders and adopt a just-in-time procurement strategy with sporadic restocking and little willingness for bulk stockpiling, failing to drive demand growth for general silica. On the contrary, numerous emerging high-end application scenarios keep expanding and boosting demand for functional silica. The tire industry continuously promotes low rolling resistance green tires and optimizes formulations, driving steady growth in demand for high-dispersion modified silica as a core reinforcing filler. The coating industry evolves toward high weather resistance, delicate matte finish and anti-settling performance, raising the proportion of matting special modified silica used in industrial paints, wood coatings and high-grade architectural coatings. In the new energy sector, expanding tracks including lithium battery separator coating, photovoltaic encapsulant adhesives and energy storage sealing materials push up demand for low-heavy-metal, high-dispersion fumed silica. In addition, sectors such as medical excipients, food-contact products and high-end silicone products enforce strict standards on silica purity and impurity control, further driving the development of the high-end customized silica market.

　　The structure of foreign trade exports continues to optimize and adjust. In the past, China’s silica exports were dominated by low-priced general precipitated products with thin profits and vulnerability to overseas trade barriers. Since this year, domestic manufacturers have gradually adjusted export portfolios and increased exports of high value-added products such as high-dispersion tire-specific silica, hydrophobically modified silica and high-purity fumed silica. New tire and coating factories in Southeast Asia and the Middle East continuously release procurement demand. European and American markets maintain stable growth in demand for low-carbon, low-impurity functional powder materials. Rising high-quality overseas orders effectively divert domestic high-end supplies, ease domestic supply pressure and provide strong support for stable prices of functional silica. Meanwhile, overseas clients pay increasing attention to supporting formulation services, and domestic raw material enterprises with joint R&D capacity achieve more growth in overseas cooperation orders.

　　Industry analysts state that the divergent pattern of the silica market will remain unchanged in the short run. General low-end precipitated silica lacks positive catalysts and is likely to continue weak fluctuations. Various functionally modified silica enjoys robust demand backed by multiple downstream sectors and firm market performance. Approaching the traditional “Golden September” chemical stocking cycle in September, tire, coating and rubber product manufacturers will gradually launch autumn stockpiling, and functional silica is expected to witness a wave of concentrated procurement. In the medium and long term, with the continuous development of the new material industry, downstream application scenarios for silica will keep expanding. The market space for low-end products used merely as basic fillers will continue to shrink, while customized, functional and special modified silica will become the main growth driver of the industry.

　　For participants across the industrial chain, downstream manufacturers can cooperate with raw material suppliers in advance to complete sample evaluation, lock in functional silica matching their formulations, reasonably arrange stocking schedules and avoid risks of tight supply in peak seasons. Upstream producers need to accelerate product portfolio adjustment, reduce output of homogeneous low-end products, increase investment in powder modification technology R&D, improve supporting downstream application services and transform from raw material suppliers into formulation solution providers. Trading and distribution enterprises can cultivate vertical segmented tracks, build differentiated supply systems and tap circulation added value of functionally modified silica. In the future, modification R&D capacity, customized service capability and low-carbon compliance level will determine the core competitiveness of silica enterprises, and the high-quality industrial transformation will keep advancing.
