Dispersible boehmites - DISPERAL / DISPAL Sasol's aluminas have high chemical purity and dispersibility. All important physical properties such as pore volume, particle size and specific surface area can be adjusted. DISPERAL® and DISPAL® are the tradenames for the high purity, highly dispersible, boehmite alumina powders and sols/dispersions manufactured by Sasol in Brunsbüttel, Germany and in Lake Charles, Louisiana, USA.
These aluminas, which are nano sized in the dispersed phase, exhibit a unique combination of purity, consistency and dispersibility that make them excellent materials for use in colloidal applications. Dispersible aluminas are applied as additives in coatings, rheology modifiers, polymer additives, abrasives, paper anti-skid, refractory, catalysts, detackifiers and washcoats for exhaust gas catalytic converters. |
