Albawhite® 40, 60, and 70 are super white, easily dispersible natural barium sulphate extenders. At the production site of Deutsche Baryt-Industrie in Bad Lauterberg in the Harz mountains, the sorted raw material is well finished by special careful dressing processes. A range of different fine products is available with a very good cost-effectiveness and a remarkably good quality overall. Very important is the high brightness as well as the low Si-content of all types, and therefore the high profitability in maintenance costs for the customer.
