In recent years, the historical structural reshaping of downstream demand pattern in China’s silica industry is taking place. The traditional consumption structure that “tire demand dominates and general materials serve as supplements”, which has lasted for many years, has been completely broken. The rapid volume growth in new energy and new material sectors keeps expanding silica’s application scenarios and accelerating product upgrading. It has officially replaced the traditional tire market and become the core track with the largest increment and fastest growth rate in the silica industry. For a long time, more than 60% of the consumption of domestic precipitated silica was concentrated in the rubber tire sector. The prosperity of the industry was highly dependent on automobile supporting, tire exports and the operation status of rubber products. The market growth pace was relatively slow, product iteration lagged, and homogeneous competition was severe. However, as China’s new energy industry enters a large-scale explosive cycle, the demand for silica from power batteries, energy storage, supporting materials for new energy vehicles, photovoltaic auxiliary materials, electronic insulation materials and other emerging sectors keeps surging. This has completely rewritten the traditional demand structure of silica and driven the transformation of the industry from traditional chemical auxiliary raw materials to high-end functional new materials.
In the field of new energy power batteries, modified silica has become an indispensable key functional powder in diaphragm coatings, electrolyte additives, battery sealing structural parts and insulating thermal conductive materials. Nano silica used for lithium battery diaphragms, after precise surface modification, features high purity, low impurities, high heat resistance and excellent dispersibility. It can form a uniform and dense ceramic coating on the diaphragm surface, effectively improving the high-temperature shrinkage resistance, puncture strength and insulation stability of the diaphragm, and greatly reducing the risk of thermal runaway of power batteries under high temperature, high pressure and fast charging conditions. It is a core auxiliary material to improve the safety performance of lithium batteries. With the continuous improvement of power battery energy density, the full popularization of fast charging technology and the large-scale implementation of energy storage power stations, the downstream demand for high-end silica with ultra-high purity, low metal ions and excellent batch stability keeps rising. Its access threshold, certification cycle and technical standards are far higher than those of the traditional tire market, forming an independent high-end powder market with rigid demand.
Besides the lithium battery track, lightweighting, sealing and anti-corrosion, and interior modification of new energy vehicles continuously drive the consumption of functional silica. New energy vehicles extensively adopt silicone rubber sealing strips, waterproof sealants, damping materials and plastic modified components. As a core filler for reinforcement, toughening, wear resistance and weather resistance, modified silica can significantly improve the mechanical properties and aging resistance of polymer materials, adapting to the complex working conditions of new energy vehicles such as long-term outdoor use, frequent vibration and alternating high and low temperatures. Compared with fuel vehicles, new energy vehicles put forward higher requirements for material safety, weather resistance and stability, forcing powder enterprises to continuously optimize product purity, dispersibility and yellowing resistance, and driving the iteration and volume expansion of high-end customized silica.
Although the traditional tire market still maintains stable rigid demand, its growth momentum has slowed down obviously. The capacity of China’s tire industry tends to be saturated, and the export market continues to face pressure affected by overseas trade barriers and anti-dumping policies. Coupled with the slow growth of replacement demand in the tire industry, general silica for traditional tires has entered the stage of stock competition with limited room for market growth. At present, the demand growth of the tire industry no longer relies on general silica, but focuses on high-end modified silica with low rolling resistance, high wear resistance and high dispersibility. The application proportion of ordinary low-end silica in tire systems keeps declining, and the structural contradiction of surplus low-end capacity and shortage of high-end supply in the industry is further prominent.
In traditional segmented fields such as coatings, adhesives, silicone rubber and fine chemicals, the demand for silica also shows an upgrading trend toward high-end and functional products. Water-based environmental coatings, industrial anti-corrosion coatings and high-end matte topcoats no longer require ordinary filling silica, but special modified powder with controllable matting efficiency, high transparency, strong weather resistance and excellent anti-sedimentation effect. High-end silicone sealants, electronic adhesives and photovoltaic structural adhesives require silica of high purity, low moisture content and stable reinforcing effect to meet the long-term service requirements of precision electronics and outdoor photovoltaic modules. Traditional general silica can no longer match the upgrading pace of downstream high-end materials, and market demand continues to shrink.
The subversive change in demand structure is forcing the overall reconstruction of capacity structure, technical routes and corporate strategies of the entire silica industry. The previous development model of massively expanding the production capacity of general precipitated silica and selling products at low prices has completely failed. The profit focus of the industry has fully shifted to high-purity, modified, functional and customized high-end powder products. Leading enterprises with continuous R&D capabilities, capable of developing special grades for new energy scenarios and holding long-term customer certification qualifications for batteries enjoy sufficient orders, stable premium and continuous profit growth. In contrast, small and medium-sized enterprises focusing on low-end general products, lacking modification technologies and high-end customer certifications are continuously faced with shrinking orders, fierce price competition, profit losses and insufficient operation rates, accelerating the capacity elimination in the industry.
From the perspective of import and export pattern, the domestic substitution of high-end new-energy-grade silica in China keeps accelerating. In the past, domestic high-end functional silica relied heavily on imports. Overseas brands occupied the domestic high-end market by virtue of technical barriers, stable batch control and comprehensive application supporting services. As domestic leading enterprises continuously break through core technologies including powder modification, purification and precision particle size control, the performance indicators of domestic high-end silica have reached or even surpassed imported products. They have successively entered the supply chains of leading domestic battery enterprises, new energy material enterprises and photovoltaic enterprises. The space for domestic substitution keeps expanding. Meanwhile, high-end domestic powder is exported overseas in batches, gradually building the global competitiveness of domestic high-end powder materials.
Industry institutions conclude that the silica industry has fully entered a new development cycle featured by “new energy-driven, high-end product-oriented and technology-dominated market competition”. Future industry growth will no longer depend on the stock demand of traditional rubber and tires, but be continuously driven by emerging incremental tracks such as new energy, high-end new materials and precision electronic materials. Industrial competition will shift from simple cost and capacity competition to comprehensive competition covering technological iteration, formula customization, application services and quality stability. With the continuous expansion of the downstream new energy industry and accelerated iteration of new materials, the market space of high-end functional silica will keep broadening. The structural bull market of the industry will continue for a long time, promoting China’s silica industry to completely get rid of low-end involution and achieve leapfrog development toward high quality, high-end positioning and high added value.
