At the end of August 2026, China’s chemical industry remains in the traditional summer off‑season. High temperatures curb operating rates of downstream sectors including rubber, composite materials and coatings. Coupled with production constraints from energy‑consumption control, most downstream enterprises adopt a low‑inventory operation mode and mainly purchase goods on an as‑needed basis. Although the market holds certain expectations for the traditional Golden‑September peak season, solid signals of real end‑user consumption recovery are still absent, and wait‑and‑see sentiment prevails. The silica industry has departed from the era of universal price rises or falls and shifted toward structural differentiation. Conventional precipitated silica is trapped in dilemmas of sluggish demand, high inventory and squeezed profits. By contrast, high‑end modified silica applied in new‑energy tires, organosilicon sealing systems, photovoltaic auxiliary materials and electronic encapsulation materials boasts robust demand resilience and serves as the core growth engine of the industry. Intertwined factors such as raw‑material costs, capacity iteration, downstream industrial transformation and international carbon‑trade rules are reshaping the competitive landscape of the whole sector.

  In the upstream raw‑material segment, restricted by plant maintenance and energy‑consumption quotas, sodium silicate, the core feedstock for precipitated silica, sees limited effective supply and maintains high prices, delivering rigid cost support for finished silica products. The sulfuric‑acid market is adequately supplied. However, downstream fertilizer sectors are in the off‑season with weak purchasing demand, and sulfuric‑acid prices fluctuate at low levels, partially offsetting cost increases brought by sodium silicate. Summer industrial power consumption hits annual peaks, pushing up energy costs and further raising comprehensive production costs of precipitated silica. Faced with rising raw‑material and energy expenses, numerous small‑and‑medium‑sized manufacturers suffer continuous profit‑margin squeeze for general‑purpose grades. Some enterprises voluntarily lower plant operating rates to restrain low‑price goods from entering the spot market and avoid loss risks. No drastic fluctuations occur in raw‑material markets, yet a solid cost base strongly underpins finished‑product quotations.

  On the supply side, the overall operating rate of domestic precipitated silica stays at 70‑72%. Domestic total capacity is enormous, while operating rates vary widely among enterprises. Backed by long‑term stable orders, leading enterprises maintain relatively high‑load plant operation and keep upgrading product mix. They cut output of low‑value‑added ordinary rubber‑grade silica and divert more capacity toward high‑dispersion and surface‑modified special‑purpose products. Small‑and‑medium‑sized enterprises bear dual pressures from rising costs and vicious low‑price competition. They adjust operating rates flexibly according to market conditions, prioritize order delivery for long‑term clients and voluntarily reduce spot‑market supply. Few new‑capacity projects build traditional general‑purpose precipitated‑silica lines; most focus on high‑value‑added tracks such as new‑energy tires, organosilicon products and electronic supporting materials. Inventory divergence is prominent. General‑purpose grades for tire filling and common rubber goods hold medium‑to‑high inventory, bringing heavy de‑stocking pressure. Modified silica for new‑energy and photovoltaic‑energy‑storage applications is in tight supply, and order backlogs of many manufacturers extend to mid‑to‑late September. The fumed‑silica market also shows obvious differentiation. Ordinary hydrophilic products face fierce competition with sideways prices, while high‑end special grades for electronic and photovoltaic adhesives are supply‑constrained by organosilicon monomers and enjoy strong bargaining power.

  Downstream markets feature weak real‑time demand alongside rising peak‑season expectations. Tires remain the largest consumption market for silica. Domestic tire enterprises maintain operating rates of 72‑77%. Downstream factories mainly adopt purchase‑on‑demand strategies without large‑scale centralized restocking. The traditional replacement‑tire market is dominated by stock‑based demand with limited short‑term increments. The steadily expanding green‑tire industry for new‑energy vehicles continuously fuels demand for high‑dispersion silica. Downstream buyers keep raising requirements for impurity control, batch consistency and carbon‑footprint indicators, which constitutes the most important growth driver for the tire segment. Silicone rubber and sealants deliver strong anti‑cyclical performance. Sustained order releases of photovoltaic‑energy‑storage‑related adhesives drive stable consumption of reinforcing silica. Traditional sectors including coatings, feed additives and daily‑chemicals see stable demand with limited new orders, dominated by stock‑market competition. Approaching the September peak season, only a small number of downstream enterprises conduct small‑batch tentative stock‑up; most remain cautious and large‑scale restocking has not materialized.

  Profound changes have taken place in export patterns, bringing both structural opportunities and pressures. General‑purpose silica products face impacts from overseas local‑capacity expansion and multi‑country competitors. Price suppression by overseas buyers is common, and export resistance for ordinary grades keeps mounting. Benefiting from reliable product quality, high‑dispersion modified special‑purpose silica achieves steady growth in overseas orders. Relevant overseas carbon‑border‑trade policies are gradually implemented. Importers continuously raise review thresholds for carbon footprint, production traceability and compliance documents, and enterprises without green‑process upgrading encounter export obstacles. The survival space for the previous low‑price‑high‑volume export model keeps shrinking. Enterprises with completed low‑carbon‑process renovation and sound carbon‑accounting systems gain growing overseas competitive advantages. Export competition has evolved from simple price rivalry into comprehensive‑strength competition covering product quality, carbon‑management capabilities and customized services.

  In terms of enterprise operation, profit bipolarization across the industry keeps intensifying. SMEs focusing on general‑purpose grades mostly operate on slim profits and face loss‑making risks in certain periods under dual squeeze from rising costs and vicious low‑price competition. Enterprises specializing in high‑end modified‑product business maintain favorable profitability relying on technical accumulation and tight market supply. The proportion of R&D investment across the whole industry rises steadily. More enterprises enter emerging downstream tracks, optimize product portfolios and reduce the proportion of low‑end‑product businesses. Industrial reshuffling moves forward steadily. Small‑and‑medium‑sized capacities lacking technical reserves and competent cost‑control capabilities are under mounting survival pressure, and the phase‑out pace of backward capacities accelerates moderately.

  Market outlook: the off‑season trend will continue in the short run, and quotations for general‑purpose silica grades remain weak‑stable. Solid cost support limits downside risks; the recovery of real downstream demand is slow, peak‑season expectations have not been fulfilled, upward driving force is insufficient, and the probability of sharp price swings is low. Supported by demand from new‑energy and organosilicon tracks, high‑end modified special‑purpose grades keep firm market sentiment, and some short‑supplied grades enjoy premium space. After entering September, close attention shall be paid to production‑recovery amplitude and actual restocking intensity of tire, rubber‑goods and sealant manufacturers, as well as continuity of overseas orders and release rhythm of new high‑end special‑purpose capacities. In the medium‑and‑long‑term perspective, energy‑consumption control, environmental‑protection policies and overseas carbon‑trade barriers will keep phasing out backward capacities. Enterprise competition is no longer simply about capacity scale, but focuses on comprehensive strengths including modification technologies, cost control and full‑chain green‑manufacturing capabilities. The major trend of the silica industry toward high‑end specialization will keep advancing.
