4. What’s the related effects of fumed silica?
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 used as anti-caking agent; for liquid products, HIFULL fumed silica used as anti-settling agent or suspending agent.
