Albasoft® 100 is an extremely white, highly dispersed barium sulphate extender. At the production site of Deutsche Baryt-Industrie in Bad Lauterberg in the Harz mountains, the sorted raw material is processed by means of special preparation and refining methods. Furthermore, the material is well finished by milling in a modern type of jet mill. The product is free from calcium carbonate and has a reliably low yellowish index.
