Applications         
Due to its special pore structure SG-7 wide porous, white

is applied for many technical processes:

Catalyst and catalyst carrier in varied chemical and

petro-chemical operations.Separation and purification of active components in biomedicine and preparation of high purity substances.

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-5 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.
