DISPAL / DISPERAL
DISPERAL and DISPAL are the trademarks for the high-purity, highly dispersible boehmite powders and sols/dispersions manufactured by Sasol in Brunsbüttel, Germany, and in Lake Charles, Louisiana, USA. In the dispersed phase these boehmites, exhibit a unique combination of purity, consistency and dispersibility that make them excellent materials for use in colloidal applications. The Sasol range of dispersible boehmites has traditionally been used in applications such as sol-gel ceramics, catalysis, refractory materials, rheology control and surface frictionising.
Other applications include surface coating as well as paint detackification, polymer-additives and functional fillers
