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

Selective adsorption separation of organic gas or liquid.

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.
