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.

HC-380 is hydrophilic fumed silica with a specific surface area of 380 m2/g 

Properties: 
 Rheology & Thixotropy control                         Reinforcement
 Free flow aid and anti-caking aid for powders           Antisagging & Antisettling
 Thickening                                            Good transparency performance
