Fumed silica
★ Sealed storage: Store in a low temperature, ventilated and dry place.
★ Storage period: at least two years under normal storage conditions.
Fumed white carbon black is also called fumed silica. White amorphous and highly dispersed fine powder. Has high dispersion performance. Soluble in caustic potassium (sodium) and hydrofluoric acid. Insoluble in water and other acids.
Absorb moisture in the air to form aggregated fine particles. Stable to chemicals. High temperature resistance. Does not burn. Has high electrical insulation. Has a high thickening and thixotropic effect. Good adsorption and reinforcement. Used as a thickener and thixotropic agent for plastics and coatings, silicone rubber reinforcing agent, plastic film opening agent, powder anti-caking agent, pharmaceutical excipient, cosmetic performance improver, sealing material, electrical insulation, thermal insulation , Ink and so on.
