    Inventors: Uwe Schachtely, Christian Panz, Ralf Schmoll
  • High-whiteness, non-heat-treated hydrophobic precipitated silica
    Patent number: 6899951
    Abstract: The present invention provides a hydrophobic precipitated silica having the following properties: carbon content 1.0-8.0% methanol wettability ?20-55% reflectance >94% BET/CTAB ratio ??1 DBP absorption <250 g/100 g BET surface area ?50-110 m2/g CTAB surface area 100-150 m2/g Sears number <13. The present invention also provides methods for making and using the hydrophobic precipitated silica and articles and compositions which include the same.
