HYSG-81SILICAGEL wet, powdery

Silica gel, little wet, nanometer powder, a

superparticulate material with a very high purity of

approx.99.5% SiO2 (dry basis) and a large mean pore diameter of approx. 100 Å. With good stability, porous structure and large surface area, it is an excellent adsorbent and filter aids. without signifi-cantly 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-81 wide porous, white is applied for many technical processes:

Adsorbent and filter aids in varied chemical and

petro-chemical operations.

Additives and filter aids for food and beverage industris.

Beer refining

Dehydration and purification of liquids

The temperature at reactivation should not exceed 180 °C. 

Packing            
Airtight in 10 kg bags,400KG big bags with PE-Inliner.

Handling           
SG-81 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.
