Advantages of Calcined Neuburg Siliceous Earth

Properties of Calcined Neuburg Siliceous Earth and advantages for users: 
 

• low moisture content, low moisture absorption
  → lower risk of blistering for pressureless vulcanization
   
• very low chloride content
  → prevention of anti-corrosion
   
• very high brightness and color neutrality
  → for white products without yellowness, less need for white pigments like titanium dioxide
   
• optimum dispersion properties even in critical compounds, comparable with puriss products
  → short mixing times, no agglomerates
   
• avoids mold fouling/deposits on dies caused by filler
  → high productivity and low costs thanks to reduction of stoppages for cleaning and prevention of waste
   
• very fine cell structure in sponge and microcellular rubber
  → high quality sponge and expanded rubber products
   
• low dielectric loss in high voltage insulation
  → reduced energy losses in electric power transmission
   
• potential for lower compression set
  → improved long-term sealing effect, for greater flexibility in creating recipes
   
• potential for improved oil resistance
  → combined with the very low compression set for meeting high demands for sealing
   
• very low CO₂-footprint
  → reduction of product carbon footprint of rubber compounds
