The plastics processing industry currently faces drastic changes. Processes and strategies to allow for a more sustainable production have to be implemented. However, due to the often fluctuating quality the use of recycled materials creates many additional challenges. A reliable quality control is required to support the transition process.
Besides mechanical testing liquid chromatography, specifically GPC/SEC, is one of the techniques applied to learn more about material properties. A recently published Tip&Trick summarizes how GPC/SEC can help to investigate the quality of materials containing recycled portions.
