Fumed silica is a high value-added fine chemical product; it is a white, loose, amorphous, non-toxic, non-polluting inorganic non-metallic oxide.The primary particle size betweens 7 ~ 40nm and the specific surface area is generally greater than 100m2 / g. Because of its nano-effects, in the material the fumed silica exhibits excellent properties of reinforcing, thickening, thixotropic, insulation, matting, anti-sagging, which are widely used in the silicone rubber (polyester plastics, sealing materials,etc.), siliconeglue (adhesives,paints,coatings,etc.)and high-performance fibers, new synthetic unsaturated resin, electric insulation, inks, pharmaceuticals, paper, food, cosmetics, chemical mechanical polishing, etc., to be known as the "industrial MSG".

气相二氧化硅是一种高附加值的精细化工产品，它是一种白色，疏松，无定形，无毒，无污染的无机非金属氧化物。原始粒径在7〜40nm之间，比表面积一般大于100m2 / g。由于其纳米效应，在气相二氧化硅材料中，硅橡胶（聚酯塑料，密封材料等）广泛应用，具有增强，增稠，触变，绝缘，消光，抗流挂等优异性能，被称为“工业味精”的硅胶（粘合剂，油漆，涂料等）和高性能纤维，新型合成不饱和树脂，电绝缘材料，油墨，医药，造纸，食品，化妆品， ”。
