(Industry Flash, April 19, 2026)At present, silica, a traditional chemical raw material, is rapidly expanding beyond conventional applications such as rubber and tires. With its excellent reinforcing, insulating, wear-resistant and optical properties, it is quickly penetrating emerging sectors including photovoltaic encapsulant films, electronic potting adhesives, and lightweight composite materials, becoming an important growth driver in the silicon-based new materials sector.
Different from the past when growth relied heavily on the tire industry, demand for silica in the new energy sector has grown significantly faster than in traditional fields since the beginning of this year. To improve weather resistance and light transmittance, photovoltaic encapsulant films extensively use special fumed silica as a modifying additive, with market demand surging by more than 30% year-on-year. In the electronics and electrical sector, rising demand for flame-retardant and insulating silicone rubber products has driven continuous growth in orders for high-purity, low-metal-ion silica.
As application scenarios continue to expand, the product structure of the silica industry is undergoing a notable shift. Fumed silica, featuring high purity and good dispersibility, is in strong demand in high-end manufacturing, with stable prices and profit margins. Meanwhile, traditional precipitated silica producers are adjusting their R&D strategies to develop specialized grades for photovoltaic, electronic, medical and other applications, pursuing differentiated competition.
Industry insiders pointed out that the silica industry was frequently affected by raw material prices and tire industry cycles in the past. Today, with the expansion of cross-border applications, its risk resistance has been notably enhanced. Several enterprises stated that they have prioritized photovoltaic-grade and electronic-grade silica as key R&D directions, with related capacity plans gradually being implemented.
Going forward, amid the continuous expansion of new energy and high-end manufacturing industries, silica will further transform from a "traditional filler" to a "functional new material". Enterprises capable of specialized, refined and high-purity production will embrace broader market prospects.
