Silica Extinction Powder (Ns-a160)

These Silica Extinction Powder (NS-A160) is white flocculent powder, non-to poisonous, odorless, non-flammable, non poisonous not dissolve in acid, alkali and all kinds of organic solvents, soluble in hydrofluoric acid, strong base. Stable chemical properties since it is not decomposed or discolored in high temperature and direct sunlight.Due to its big specific surface-area and mass hole chaetomium, it has fine effect of extinction thickening and scratch-resistant flowers.
