17-09: Time and Temperature Dependent Mechanical Behavior of PP Fills Use of Biocides

17-09: Time and Temperature Dependent Mechanical Behavior of PP Fills Use of BiocidesMechanical behavior of plastic components are not only dependent on the pure load or load case (e. g. bending vs. pure compression), but also on the loading time and temperature. The impact of these two factors will be discussed in this paper based on different testing results for polypropylene. Additionally a simplified viscoelastic model has been derived from that data to get a general idea for the engineering of plastic fills.

Limited water resources combined with wastewater discharge concerns have made water reuse a growing focus of the industry
