Cleanroom-Suitable Materials

© Fraunhofer IPA, Rainer Bez

In many industries (e.g. semiconductor, medical device, optics or display manufacture), a growing number of products need to be manufactured under highly clean conditions. Since the tiniest amounts of contamination in the production process can cause major faults and losses, the demand for cleanroom-suitable materials is constantly rising. In view of this, the market is increasingly calling for a practical and reliable method to assess the cleanliness properties of all materials used. Cleanliness suitability and cleanroom suitability are key technical performance characteristics. The cleanliness requirements of materials depend on the technological requirements of the industry concerned:

  • Particle emissions from material pairings
  • Biological resistance (ability to resist metabolism)
  • Chemical resistance
  • Antibacterial efficacy (microbicidity)
  • Outgassing behavior of material samples
  • Verification of cleanability using fluorescing test contamination (riboflavin test)
  • H2O2 absorption/desorption


If no standards or procedures exist for the qualification tasks we are set, we develop methodically-assured test procedures based on our wealth of knowledge and experience.
