Silica Gel is a regenerative absorbent consisting of amorphous silica, which is produced in the form of irregular crystals and as per IS:3401:1979.
Silica Gel can be used as dehumidifying and dehydrating agent in air-conditioning, drying of compressed air and other gases and liquids, such as refrigerants and oils containing water in suspension,recovery of natural gasoline from natural gas, bleaching of petroleum oil,s catalyst and catalyst carrier, chromatography, anticaking agent in cosmetics and pharmaceuticals as waxes to prevent sliping in dietary supplements.
SILICA GEL WHITE is Non-Indicative Type silica gel, So it is not possible to ascertain, whether it has completely absorbed moisture or not.
SILICA GEL BLUE is produced by impregnating White Silica Gel with Cobalt Chloride which in its dehydrated from is blue in colour but changes to pink when it absorbs moisture to it capacity. The change in colour may be repeated time and again to indicate whether it needs regeneration or not.
Silica Gel Blue cannot be used as moisture indicator in the drying of gases containing ammonia,as the Cobalt Salt forms a stable deep blue compound with ammonia.Silica Gel blue is also not recommended for use in automatic air dryers.
SILICA GEL BAGS (BLUE & WHITE):
Silica Gel in cloth & Non-Wooven Paper Bags packing are also available in various sizes like 1gm, 2gms, 5gms, 10gms,50gms, 100gms and in any other size as per your requirements. These bags has widely used in Pharmaceuticals, Leather goods, Food 7 Machinery Components etc., as preservative for prolonged storing and prevents deteriorating of properties and appearance due to moisture.
