Hydrolic Fumed Silica Fusil 200
Fumed silica is the superfine micro-nano fine chemical product, which is divided into hydrolic type and hydrobic type in accordance with their different surface treatments.
Its appearance is white powder. Native particle size ranges from 5nm-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.
