Advantages in thermoplastic molded parts

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, morphology
  → high surface quality, no spots or agglomerates, supports pigment dispersion (spacer effect), potential pigment savings
   
• high brightness and color neutrality
  → enables white products without a yellow tint, low requirement for white pigments such as titanium dioxide
   
• largely isotropic properties
  → low warpage, medium increase in stiffness
   
• hard silicate mineral
  → very good acid resistance, abrasion resistance, scratch resistance
   
• polymer-specific adaptation via functionalization
  → very good scratch resistance, high impact strength, high ulitmate elongation
   
• temperature resistance
  → can also be used for technical thermoplastics, no by-products or decomposition
   
• low CO₂-footprint
  → reduction of product carbon footprint of thermoplastic molded parts
