In 2023, China accounted for 35% of global fumed silica production capacity (up sharply from just 12% in 2018), with exports of high-end products soaring 87% year-on-year. Domestic products are priced at 60% of imported equivalents while delivering comparable performance.

Key Specifications:
1.Specific surface area: 400±15 m²/g (matching Evonik's AEROSIL®380)
2.Primary application: Widely adopted in new energy battery separator coatings for enhanced performance

Industry Impact:
The rapid expansion reflects China's growing technological prowess in advanced materials, particularly for lithium-ion battery applications where modified fumed silica significantly improves separator performance.
