In Germany, Austria, Switzerland, the Netherlands, Italy, Slovenia and Croatia, the Amberger Kaolinwerke distributes paper kaolins produced by BASF AG, formerly Engelhard Corp., USA.
The characteristic features of these kaolins, produced externally, are their small grain size and high degree of whiteness. They are primarily used in the manufacture of paper for offset printing.
BASF also offers calcine kaolin Ansilex ® 93 , a product for improving opacity.
