TOROWHITE (Toro Gips) FIL 04 is a Calcium Sulfate Anhydrite (AII) functional additive with very high purity & good whiteness. FIL 04 is produced from specially selected Food & Pharma Grade natural gypsum. Narrow particle size distribution enables high performance in terms of thermal and mechanical characteristics, dimensional stability, optical properties and processability. Made by controlled dehydration of Calcium Sulfate Dihydrate at high temperature it is known as «insoluble» Anhydrite II due to its very low absorption of water.
