Fumed silica is the superfine micro-nano fantastic chemical item, which is divided into hydrophilic variety and hydrophobic type in accordance
with their various area treatments. Its appearance is white powder. Indigenous particle dimension ranges from 5nm to 40nm, with important
features of thixotropy, reinforcing, thickening and filling. Consequently, it is widely utilised in the EPT of rubber, sealant, plastic, resin,
paint, printing ink, papermaking, drugs, cosmetics, foodstuff etc.
HC-150 is hydrophilic fumed silica with a specific surface area spot of a hundred and fifty m2/g
