SILICA WITH REDUCED TRIBO-CHARGE FOR TONER APPLICATIONS

Surface-treated fumed silica, with a tribo-electro static charge of −500 μC/g to +500 μC/g, a ratio of the tribo-electro static charge to BET surface area of −3.5 μC/m2 to +3.5 μC/m2, a methanol wettability of at least 20% by volume methanol in methanol/water mixture, a ratio of carbon content to BE...

More Information
Summary:Surface-treated fumed silica, with a tribo-electro static charge of −500 μC/g to +500 μC/g, a ratio of the tribo-electro static charge to BET surface area of −3.5 μC/m2 to +3.5 μC/m2, a methanol wettability of at least 20% by volume methanol in methanol/water mixture, a ratio of carbon content to BET surface area of at most 0.020 wt. %*g/m2, a process for its preparation and the use thereof.
