The Application of Fumed Silica As Additive In The Resins Industry
What to do when unsaturated polyester resin has bad performance in mechanical and tensile strength?
HIFULL fumed silica can solve these problems:
Fumed silica is an inorganic reinforcing material that can improve the hardness, mechanical strength, and ductility of UPR.
HIFULL fumed silica also has excellent thickening and thixotropic properties, anti-settling, reinforcing, increased wear resistance, and anti-aging effects, and is widely used in epoxy resin, gel coat and phenolic resins.

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.
