When fumed silica is used as filler or additives, it helps in thickening, reinforcement, transparency, free-flow, thixotropic performance, dielectric properties, anti-settling, heat insulation, and anti-sagging. For example, for powder products, HIFULL fumed silica is used as an anti-caking agent; for liquid products, HIFULL fumed silica is used as an anti-settling agent or suspending agent.

Quality Stabilization: we are the earliest fumed silica manufacturers with independent R&D in China, which guarantees our product stabilization.
Largest Manufacturer: Our annual output of fumed silica is about 12,000 tons.
Strong R&D Team: Besides our own R&D institute and application& technology department, we’ve to build a research center with Sichuan University and Wuhan University, both are top-tier universities in China.
Leading Authority: We have already been the influential enterprise in the silicon industry in China. Doctor Wang Yuelin, the actual controller of Hifull, is the leader of the Sino-Germany project ISO18473-3 << Fumed Silica for Silicon Rubber>> and he is granted the Outstanding Contribution Award by the committee.
