HYSG-8SILICAGEL wide porous, beads

Silica gel, white beads with a very high purity of pprox.

99.5% SiO2 (dry basis) and a large mean pore diameter of

approx. 100 Å. SG-8 wide 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-8 wide 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 180 °C. 

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

Handling           
SG-8 wide porous, beads 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.
