Product Description
Hot Sale Rubber Auxiliary Agents Silicon Dioxide Nano Hydrophilic Fumed Silica 380 (Surface Area 380 m2/g)
Products DescriptionFumed 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-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, cosmetics, food etc.
