Colloidal Silicon Dioxide Hydrophilic And Hydrophobic Fumed Silica Pyrogenic Silica Nano Silica Powder/Fusil200
Product Description
Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrophilic type and hydrophobic type in accordance with their different surface treatments. Its appearance is white powder. Native particle size ranges from 5nm to 40nm, with significant functions of thixotropy, reinforcing, thickening and filling. Therefore, it is widely used in the industries of rubber, sealant, plastic, resin, paint, printing ink, papermaking, medicine, cosmetics, food etc.

Company Information
Dalian Fuchang Chemical Group Co., Ltd. is a company that is engaged in scientific research, manufacturing and trade. Currently, we have become one of the largest comprehensive chemical groups in Northeast China and own two high-grade quartz mines so that a solid foundation for producing high quality products can be layed. We successively set up large manufacturing bases in Inner Mongolia Chifeng, Jilin Tonghua, Liaoning Jinzhou and Jiangxi to manufacture series of silicon dioxide products. The company has cooperated with many domestic research institutions, adopted advanced production technology, combines with perfect management system and detection means and achieves 4000 tons of fumed silica, 30000 tons of precipitated silica, 1200 tons of silica matting agent, 8000 tons of fused silica. The quality has reached international first-class level, and some models can completely replace imported products. Meanwhile, by recycling its own by products and utilization, Fuchang has reached an annual output of 1,500 tons of sodium aluminosilicate, which meets needs of different customers and reduces business cost at the same time. Our products have passed ISO9001: 2000 International Quality System Certification, SGS Heavy Metal Detection etc. and are sold to dozens of countries and regions, e.g., India, IraBrazil, Indonesia, Vietnam, Thailand, Turkey, Pakistan, South Korea, United States, Japan, Germany, Korea and Russia.etc.
