By the end of August 2026, China’s chemical industry remains in the traditional summer off‑season. Sustained high temperatures depress operating rates of downstream sectors including rubber, sealants, coatings and composite materials. Coupled with production constraints from energy‑consumption control, downstream enterprises generally adopt a low‑inventory strategy, and on‑demand purchasing has become mainstream. As the traditional Golden‑September peak draws near, certain restocking expectations exist in the market. Nevertheless, real terminal consumption recovery remains limited, and wait‑and‑see sentiment pervades the whole industry. The silica industry has moved away from the extensive development phase featured by universal price rises and falls. Market contradictions are mainly reflected in product‑structure gaps. Conventional precipitated silica faces real‑world dilemmas such as sluggish demand, continuous inventory accumulation and shrinking profit margins. In contrast, modified silica applied in new‑energy tires, organosilicon sealing systems, photovoltaic auxiliary materials and electronic encapsulation materials demonstrates solid demand resilience and serves as the core growth driver of the industry. Intertwined factors including raw‑material cost fluctuations, capacity‑structure iteration, downstream industrial upgrading and rising overseas carbon‑trade barriers keep reshaping the industrial competitive landscape.

  In the upstream raw‑material segment, restricted by plant maintenance and energy‑consumption quota control, sodium silicate, the core feedstock for precipitated silica, sees insufficient effective supply and maintains high‑price levels, delivering rigid cost support for finished silica products. The sulfuric‑acid market is well‑supplied. However, downstream fertilizer sectors enter the demand off‑season with falling purchasing volume and low‑level fluctuating prices, which partially offsets cost increases brought by sodium silicate. Summer power‑consumption peaks push up industrial electricity costs and further raise overall production costs of precipitated silica. Numerous domestic small‑and‑medium‑sized manufacturers are under pressure from simultaneous rises in raw‑material and energy costs, and profit margins of general‑purpose grades keep being squeezed. Some enterprises voluntarily lower plant operating loads to curb low‑price goods from flowing into the spot market so as to avoid loss risks. No extreme price surges or collapses occur in raw‑material markets, yet the solid cost base provides strong underpinning for silica product quotations.

  On the supply side, the overall operating rate of domestic precipitated silica stays at 70‑72%. The industry boasts huge total capacity, while development gaps among enterprises keep widening. Backed by sufficient long‑term agreement orders, leading enterprises maintain stable high‑load plant operation and continuously advance product‑mix upgrading. They cut output of low‑value‑added ordinary rubber‑grade silica and divert more capacity toward high‑dispersion and surface‑modified special‑purpose products. Suffering dual pressures of rising costs and vicious low‑price competition, small‑and‑medium‑sized enterprises flexibly adjust operating rates according to market conditions. They prioritize order delivery for long‑term clients and voluntarily reduce spot‑market shipments. Few new‑capacity projects build conventional general‑purpose production lines. Most new projects target 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 articles hold medium‑to‑high inventory, bringing notable de‑stocking pressure. Modified silica for new‑energy and photovoltaic‑energy‑storage sectors is in tight supply, and order backlogs of many manufacturers extend to mid‑to‑late September. The fumed‑silica market also presents divergent trends. Ordinary hydrophilic grades face fierce competition with sideways price fluctuations. High‑end grades for electronic and photovoltaic adhesives are supply‑constrained by organosilicon monomers and enjoy strong market bargaining power.

  The downstream market shows a pattern of weak real‑time demand alongside rising peak‑season expectations. Tires remain the largest consumption field for silica. Domestic tire enterprises maintain operating rates of 72‑77%. Downstream factories stick to on‑demand purchasing, and large‑scale centralized restocking has not taken place. The traditional replacement‑tire market is dominated by stock‑based demand with limited short‑term new‑growth space. Continuous expansion of green tires for new‑energy‑vehicle applications steadily boosts demand for high‑dispersion silica. Downstream buyers keep raising requirements for impurity control, batch consistency and carbon‑footprint indicators, which forms an important growth source for the tire segment. Silicone rubber and sealants feature strong anti‑volatility capability. Sustained order releases of photovoltaic‑energy‑storage‑supporting adhesives drive stable consumption of reinforcing silica. Traditional sectors including coatings, feed additives and daily‑chemicals see steady demand with limited new orders, dominated by stock‑based competition. Approaching the September peak season, only a small number of downstream enterprises carry out small‑batch tentative stock‑up. Most market participants remain cautious, and large‑scale restocking has not materialized.

  The export pattern keeps evolving with both opportunities and challenges. General‑purpose silica products are impacted by overseas local‑capacity expansion and multi‑country competitors. Price suppression by overseas buyers is obvious, and export resistance for ordinary grades keeps mounting. Benefiting from stable and reliable product quality, high‑dispersion modified special‑purpose silica achieves steady growth in overseas orders. Relevant overseas carbon‑border‑trade policies keep being implemented. Importers continuously raise review thresholds for carbon footprint, production traceability and compliance documents. Enterprises without green‑process upgrading face markedly higher export difficulties. The survival space for the former low‑price‑high‑volume export model keeps shrinking. Enterprises with completed low‑carbon renovation and sound carbon‑accounting systems gain growing overseas competitive advantages. Export competition has shifted from simple price rivalry into comprehensive‑strength competition covering product quality, carbon‑management capabilities and customized services.

  From the perspective of enterprise operation, profit bipolarization across the industry further intensifies. SMEs focusing on general‑purpose‑grade products 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 deep‑engaged in high‑end modified‑product businesses maintain favorable profitability by virtue of technical accumulation and tight market supply. The proportion of R&D investment across the whole industry rises steadily. More enterprises deploy businesses in emerging downstream tracks, optimize product portfolios and reduce the proportion of low‑end 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 short‑term off‑season situation will persist, and quotations for general‑purpose silica grades remain weak‑stable. Solid cost support limits downside risks. Recovery of real downstream demand is slow, peak‑season expectations have not been fulfilled, upward driving force is insufficient, and the probability of drastic 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. Entering September, close attention shall be paid to production‑recovery performance and actual restocking scale 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 supervision and overseas carbon‑trade barriers will keep phasing out backward capacities. Industrial competition is no longer merely about capacity scale. Modification‑technology competence, cost‑control proficiency and full‑chain green‑manufacturing capabilities become core competitive factors. The general trend for the silica industry toward specialization and high‑added‑value development will remain unchanged.
