Neuburg Siliceous Earth

Filler properties and adantages in polishing and cleaning agents: 

• loose structure, close and uniform particle size distribution
  → easy incorporation into water and O/W-emulsions, excellent dispersion properties (especially puriss products), quick and easy production, very low sedimentation speed, easily re-dispersible
   
• mineralogical composition (hardness)
  → stable and constant polishing efficiency
   
• extremely low residue of > 40 µm in puriss products
  → no unwanted scratching, high gloss finish
   
• availabble in different particle sizes
  → adjustable abrasivity
   
• synergetic effect with aluminum oxide
  → for badly contaminated but sensitive surfaces, very high gloss finish, expensive aluminum oxide can be reduced
   
• good rheological properties
  → thixotropic agent, control of rheology possible, reduction of expensive additives
   
• very low electrical conductivity, no buffer effect
  → good stability in aqueous formulas, no distrubing salts/electrolytes
   
• superior chemical resistance
  → high resistance to aggressive media such as acids and bases
   
• high purity
  → also suitable for food contact incl. drinking water as per FDA and BfR regulations
