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
