HYSG-17SILICAGEL meso porous, white

Silica gel, milky white granules with a very high purity of pprox.99.5% SiO2 (dry basis) and a large mean pore diameter of approx. 60 Å. SG-17 meso porous, white can be reactivated without significantly impairing the efficiency. It is therefore very economical, easy to dispose and without any known adverse effects on the environment.

Applications        
Due to its special pore structure SG-17 meso porous, white is applied for many technical processes:

Catalyst and catalyst carrier in varied chemical and

Petro-chemical operations

Petrol refining

Dehydration and purification of liquids

The temperature at reactivation should not exceed 200 °C.

Packing             
Airtight in 20 kg cartons,bags with PE-Inliner,Airtight in 500 kg bulk bags with PE-Inliner.

Handling          
SG-17 meso porous, white must always be kept in airtight containers to avoid pre-adsorption with water vapour. Face masks should be used at continual exposure to extensive dusting.
