We measure the barrier effects of polymers and coatings to the permeation of gases and volatile substances.
Fraunhofer IVV developed a method that would allow the barrier properties of polymerfilms to be measured during the actual production process. In this way the permeation measurement of films can be speeded up considerably: Müller K.: Faster Results. Permeation Measurement of Films. Kunststoffe international 101 (2011) 7, pp. 62-67 [PDF]
We determine kinetic and thermodynamic parameters (diffusion and partition coefficients) for material transport in and through polymers and composite materials such as coated paper and cardboard. Using our in-depth expertise we build automated permeation test equipment that covers a wide temperature range to address specific issues. By developing simulation models we are able to transfer our measurement data to other materials and applications such as paper/cardboard packaging, pharmaceutical and medical products, skin models, contact materials for drinking water, and containers for technical products.
