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
