FNG waterproof Silica gel is white or light grey pellets. It is processed and formed from powders. Besides the adsorption feature possessed by ordinary silica gel, FNG silica gel also possesses good water-tolerant property, low break-down rate of reclamation and long service life, etc.
FNG waterproof silica gel can be used as acetylene adsorbent in the liquid air and liquid oxygen in gas-separation industry. FNG water-proof silica gel is also used to adsorb the acid and water in oil and the color caused by the organic solvent. There’s no impediment to the oil quality or the diesel engines when it is used for fuel purification.
