As September arrives, the domestic precipitated silica market enters its traditional consumption peak season. Nevertheless, a comprehensive price surge has not taken place, and market divergence within the industry has become increasingly prominent. The market for conventional filler‑grade precipitated silica is sufficiently supplied. Downstream purchasers remain cautious while end‑user inventory stays at a high level. Market prices hover weakly, and profit margins for manufacturers keep shrinking. In contrast, high‑end modified precipitated silica benefits from orders delivered by emerging sectors including green tires, photovoltaic sealants and new‑energy supporting materials. Product delivery cycles are extended and market prices remain firm. Leading enterprises gain considerable profit margins by virtue of stable product quality. Driven by upgraded new‑material requirements, stricter environmental regulations and rising overseas demand, industrial competition has evolved from simple price competition into comprehensive competition covering customized formulation, batch‑to‑batch consistency and eco‑friendly production capacity.

　　On the cost side, prices of core raw materials such as sodium silicate, sulfuric acid and steam fluctuate mildly this month, leading to generally stable overall production costs. Raw‑material costs no longer serve as a major driving force for precipitated silica prices. Low‑grade precipitated silica has low technical barriers. Numerous small‑and‑medium manufacturers compete for market share by low‑volume‑high‑sales strategies, resulting in fierce industrial involution. Even with falling raw‑material costs, selling prices can hardly go up. High‑end modified precipitated silica requires elaborate production procedures, rigorous impurity control and exclusive surface‑modification techniques with higher compliance costs, delivering irreplaceable performance benefits and sustaining long‑term high product added value. Continuous implementation of energy‑consumption control and environmental‑protection policies, alongside green renovations for wastewater treatment and by‑product recycling, raise industrial entry thresholds. A batch of outdated production lines failing environmental assessments gradually exit the market, further concentrating high‑quality production capacity among leading manufacturers.

　　The tire market remains the largest downstream application for precipitated silica. Operating rates have steadily picked up in the third quarter. Rising sales of new‑energy vehicles fuel capacity expansion of low‑rolling‑resistance green tires. Tire producers keep increasing the proportion of high‑dispersity precipitated silica in formulations to improve fuel efficiency, wear resistance and wet‑skid performance. Tightening global green regulations make overseas tire brands pay greater attention to carbon footprint and product stability. Export orders for domestic high‑performance precipitated silica grow steadily, consuming more high‑quality capacity from leading suppliers. The market for standard tire‑grade precipitated silica faces intense competition with impacts from low‑cost overseas supplies, maintaining profitability at a low level.

　　Non‑tire sectors emerge as new growth engines for the precipitated silica industry. The silicone sealant market keeps expanding. Photovoltaic encapsulant gels, electronic potting compounds and new‑energy wire harness sealants impose strict requirements on transparency, reinforcing performance and anti‑aging properties, creating a supply shortage of low‑impurity modified precipitated silica. In the coating industry, water‑based matte paints and anti‑corrosion industrial coatings boost demand for matting‑type precipitated silica. Purchasing volumes of high‑purity food‑safe precipitated silica keep rising for feed anti‑caking agents, food additives and pharmaceutical excipients. New application fields such as lithium‑battery separator coatings and composite materials open long‑term growth potential for high‑end functional precipitated silica.

　　Structural adjustments persist on the supply side. Most newly commissioned production capacities in recent years target high‑end specialty precipitated silica, while new projects for low‑end filler grades have almost halted. Leading enterprises keep constructing intelligent production lines equipped with automatic control systems to stabilize product indicators, reduce batch‑to‑batch performance deviations and widen the quality gap with small‑scale factories. Environmental‑protection and safety supervision become routine. Small manufacturers face heavy capital pressure for technical renovation and unstable operating rates. Market orders keep flowing toward leading enterprises with integrated industrial‑chain advantages, consolidating the winner‑takes‑all industrial pattern.

　　The foreign‑trade market continues its transformation, shifting export focus from low‑end general‑purpose products to high‑value‑added modified precipitated silica. Improving global low‑carbon trade rules prompt overseas buyers to audit carbon‑emission data across supply chains. Domestic enterprises equipped with green factories and circular‑production technologies gain stronger competitiveness in international bidding. Domestic high‑end precipitated silica accelerates import substitution and expands its global market share.

　　For the short‑term market outlook, sufficient supply and weak demand will keep conventional precipitated silica prices fluctuating within a narrow range with limited upward momentum. High‑end grades including high‑dispersity tire‑specific silica, photovoltaic‑sealant silica and coating‑matting silica will sustain firm prices supported by peak‑season restocking from downstream buyers and demand growth from emerging industries, presenting potential upward opportunities. In the long run, the precipitated silica industry will develop in three major directions: fine customization, low‑carbon eco‑friendly manufacturing and integrated technical services. Enterprises capable of rapid product‑structure iteration, stable mass supply and complete supporting technical solutions will continuously occupy high‑end niche markets and secure long‑term development dividends. With breakthroughs in China’s domestic new‑material industry, high‑end precipitated silica boasts huge import‑substitution space, driving the whole sector steadily toward a new stage of high‑quality development.
