Ceramer and Ceramerplus can also be supplied as a high purity grade for semiconductor applications.
The proportion of metal ions here lies in the lower ppm range, or in the ppb range. The proportion of iron and sodium ions, for example, can each be reduced to <1 ppm. The ionic impurity content was measured by X-ray fluorescent analysis.
Special grades with even higher purity level can be produced on request.
