Production and recycling of composite materials based on polymers and fibres : assessing the chemical complexity by thermal analysis and high end mass spectrometry

Abstract: Different lifecycle steps of products (polymers/composites) were described with pyrolysis-based analytic techniques for their chemical nature and the possibility of improving current production or recycling processes. Thermal analysis with high-resolution mass spectrometry enables molecular characterisation and chemical interpretation. The analysis of PE char from an Auger reactor shows high amounts of partially pyrolyzed feedstock, releasing alkanes, alkenes and dienes. The combination of lab-based techniques with online tracing of a pilot plant was used to determine the process performance.
