Understanding permeation (transport processes) through polymer materials is one of the keys to efficiency, service life and safety in diverse applications such as mobility, energy supply and health. Dr. Andreas Konrad, founder and managing director of Mecadi GmbH for 20 years, is an expert with many years of experience in the field of permeation and functional polymers as the person responsible for almost 2000 customer projects. Examples of Mecadi's activities as a test laboratory and development service provider are:• Customer-specific permeation and leakage measurements of materials and components for almost any gases and liquids. Current topics: hydrogen, methane• Lifetime and efficiency modelling based on permeation datae.g. vehicle parts, energy storage, packaging• Research and appraisals in the field of permeation• Modification of technical polymerse.g. additives for membranes, polyvinyl alcohol derivatives, barrier layers• Selective adsorberse.g. removal of aerosols containing pathogens, adhesive particle collectors.Please contact meby email: andreas.konrad@mecadi.comor by phone : +49 (0) 6826 - 9 33 83 0Excerpt from patent list (co-inventor) and publicationsDE4339078C2 (1993) Process for improving the flame resistance of fibrous materials while improving the resistance to fungal, pest and bacterial attack Ahead of its time: DE19520657C2 (1995) Process for the deodorization of exhaust air flows - circulation of air with separation of carbon dioxide, odorous substances and retention of pathogensEP000001090270A1 (1997) Fluid electrode system for resistive slope sensorsKarlsruhe Institute of Technology : Scientific reports FZKA 6621 ( 2002) Depletion of carbon dioxide from carbon dioxide hydrogen mixtures with amine-functionalized polymer membranes and investigations into transport and reaction processes in carbon dioxide-polymer systems(partly available in English: http://technologyreport.mecadi.com/) DE000010223345A1 (2002) Process for the production of polymer frameworks with transition metals bound to them.
