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.
