Fumed silica is a very useful industrial chemical used in a variety of industrial and consumer products. Fumed silica poses a variety of health hazards to workers in various end-use industries and to those using products that use fumed silica. 
1. in various resin additives, medicine, food and other fileds.
2. rubber, sealant, silica gel, adhesive, tile grout etc.
3. paint, coating, UPR,
4. CMP suspension etc;
5. Digital photo paper etc.

Fumed silica  is one of the extremely important high-tech ultra-fine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, resistance, and other specific properties. With its superior stability, reinforcement, thickening, and thixotropy, it has unique characteristics in many disciplines and fields, It has an irreplaceable role.
