A high level of customer satisfaction is our top priority. The most important prerequisite for this is high and consistent product quality, which is ensured by daily quality control measurements (certified according to ISO 9001 since 1998). For anti set-off powders in print industry and separating/interleaving powders in film or glass industry, quality is mainly defined by a narrow particle size distribution and a low fine dust fraction. The constant characteristics of our test dusts guarantee standard conformity and reproducibility to our customers. We can ensure this quality due to our more than 60-year experience in processes like grinding, sieving, mixing and (air) separating.
