The green upgrading of domestic manufacturing continues to advance, and the industrialization and application of new materials are accelerating. The competition logic of the powder filler industry is undergoing profound changes. In the past, market competition mainly centered on raw material procurement costs, and enterprises relied on large-scale mass production to lower quotations and win customers. At this stage, however, downstream manufacturers pay more attention to the functional characteristics, batch stability of fillers as well as supporting formulation technical services. Market demand is forcing industrial transformation. With customizable surface properties, modified silica has gradually become an indispensable key raw material in various high-end manufacturing fields, pushing the entire filler industry to shift from price competition to value competition. The market for general unmodified silica is fiercely competitive, plagued by prominent overcapacity. Corporate profit margins keep shrinking, bringing obvious pressure on development.

　　The upstream raw material market generally operates steadily. Basic raw materials including metallurgical silicon, water glass and sulfuric acid maintain a balanced supply and demand with prices fluctuating within a range, forming a relatively stable cost base for silica production. There is an evident gap in the capacity for cost pass-through among different product categories. Ordinary precipitated silica enjoys sufficient supply, and bargaining power tilts toward downstream buyers. Manufacturers struggle to pass on rising costs of energy, auxiliary materials and labor, and most enterprises have to squeeze their own profits to sustain operation. In contrast, customized modified silica features higher added value, which can cover investment in modification research and development, renovation of special production lines, and multiple rounds of performance testing, delivering stronger resistance to raw material price fluctuations. Meanwhile, energy consumption control and environmental inspections across China’s chemical sector have become routine. Clean production transformation moves forward steadily. Small and medium-sized production lines with outdated processes and substandard pollutant emissions are being phased out faster. Industrial resources keep concentrating on leading enterprises with independent R&D capabilities and complete environmental supporting systems, steadily lifting the overall standardization of the industry.

　　The supply side presents striking structural differentiation. Domestic total capacity of ordinary precipitated silica is enormous. Most domestic production bases maintain high operating rates, leading to abundant circulating supplies and heavy inventory backlogs among traders, with frequent low-price competition in the low-end market. On the contrary, high-end products such as fumed silica, modified silica specially for silicone gel, and silica used as flame-retardant fillers for power batteries are subject to multiple constraints including core preparation processes, patented modification formulas and construction cycles of dedicated production lines. Their capacity expansion is limited in the short term, keeping the market in a long-term tight supply-demand balance. In recent years, many domestic chemical enterprises have launched new fumed silica projects and technical upgrading programs to accelerate import substitution. Nevertheless, ultra-high-purity grades for semiconductor packaging and high-end medical materials still face technical barriers. Imported products retain part of the high-end market share, leaving considerable room for breakthroughs in domestic substitution. Many manufacturers have taken the initiative to optimize product mix, cut capacity for low-margin general products, and increase investment in the R&D and production of customized special modified silica to meet the long-term development needs of new energy and high-end new material industries.

　　Downstream application tracks continue to show divergent performance. Demand growth in traditional mature sectors is sluggish, while emerging high-end industries keep releasing incremental dividends. In traditional fields such as ordinary rubber spare parts, shoe-making fillers and civil interior wall coatings, terminal consumption recovery falls short of expectations. Downstream product manufacturers hold high finished goods inventory and face heavy capital turnover pressure. Their procurement strategy focuses on small on-demand replenishment with little willingness for bulk stockpiling, resulting in muted overall market trading. Supported by the continuous implementation of global low-carbon travel policies, the penetration rate of low rolling resistance tires in the green tire industry rises year by year. As a core environmental reinforcing filler, high-dispersibility modified silica enjoys stable long-term demand and supports the smooth operation of relevant products. The new energy industrial chain keeps expanding. Fields including energy storage battery separators, photovoltaic sealant and insulating components for power batteries impose strict standards on silica in terms of specific surface area, dispersion uniformity and surface hydrophobic and oleophilic properties, driving steady growth in orders for various customized special silica. In addition, emerging application scenarios such as pharmaceutical excipients, food contact materials, high-end inkjet printing inks and aerospace sealing components keep broadening the application boundaries of silica and lifting the overall growth ceiling of the industry. On the foreign trade front, the steady development of overseas rubber and coating industries underpins China’s export demand for silica. However, the Carbon Border Adjustment Mechanism, geopolitical trade frictions and volatile international shipping prices bring multiple uncertainties. Domestic exporters are gradually shifting toward high-value modified products, optimizing their overseas customer structure and avoiding vicious homogeneous competition in the low-end market.

　　On the inventory front, structural inventory divergence within the industry is further entrenched. Factory and circulation inventories of general industrial precipitated silica remain at high levels, lengthening the de-stocking cycle and creating strong resistance to short-term price increases. Most high-end modified silica adopts a make-to-order business model with persistently low spot inventory and a continuously tight supply-demand balance. Cooperation models across the upstream and downstream supply chain keep innovating and upgrading. Many large downstream manufacturers have built strict raw material access review systems and signed long-term strategic cooperation agreements with qualified silica producers to lock in supply cycles, product quality and supporting technical services in advance. This helps build a stable and reliable supply chain system and mitigate operational risks triggered by raw material price swings.

　　Industry analysts point out that the market will continue to operate under structural divergence in the short run. Prices of general silica will see volatile adjustments with a low probability of sharp rises or falls. Backed by rigid demand from downstream high-end manufacturing, customized modified silica boasts stronger market resilience and carries expectations of steady growth. With the arrival of the traditional peak sales season known as Golden September, operating rates in coatings, rubber products, adhesives and tire industries are expected to rebound and drive improved overall trading of silica. From a medium and long-term perspective, customized functions and low-carbon compliance will serve as the core development directions of the silica industry. The old development model relying on extensive capacity expansion and market grabbing through low prices is no longer viable. Enterprises’ core competitiveness in the future lies in multiple dimensions including powder modification R&D, downstream formulation technical support, full-process quality control and low-carbon clean production. Enterprises that deeply engage with high-boom tracks such as new energy, biomedicine and high-end equipment manufacturing and continuously iterate customized special modified silica products will seize opportunities amid industrial transformation and embrace broader development space.
