Advantages of Neuburg Siliceous Earth

Properties of (Calcined) Neuburg Siliceous Earth and advantages for users:
 

• low moisture, low moisture absorption
  → less effort for pre-drying, pre-drying may not be necessary, less polymer degration with hydophobic products 
   
• high fineness, very low sieve residue, excellent dispersion properties, refractive index similar to polymers
  → high surface quality, no spots or agglomerates, even matting
   
• hard silicate mineral
  → very good acid resistance, abrasion resistance, scratch resistance
   
• polymer-specific adaptation via functionalization
  → low compression set, very good abrasion and scratch resistance
   
• low CO₂-footprint
  → reduction of product carbon footprint of TPE
