Product Description

Hydrophilic fumed silica is white, innoxious, insipid, amorphous fine chemical powder.  Fumed silica with features such as small particle size, large BET surface area, high surface activity and high purity. The original particle size can be 7 – 40 nm according to system setting, and the BET surface area is 100 – 400 m2/g. Because of Nanometer Effect,  fumed silica performs excellent nature of reinforcing, thickening, thixotropy, insulation, matting, resist sagging, and it is widely used in HTV silicone rubber and RTV silicone sealant, coating, painting, unsaturated polyester (UP), insulation material, adhesive & sealant, agriculture and medical macromolecule industrial fields.
