    Additives in plastics (#338)

    Polymer additives are important for stabilization in manufacturing process and stabilization over time. This application note shows the analysis of selected a process, UV and oxidation stabilizers widely used in polymers. The samples are extracted under reflux and after polymer precipitation, the additives are analyzed by HPLC. The results are essential for quality control.

    Antioxidants in polyolefin granulate (APK #374)

    The antioxidants/UV stabilizers in the polyolefin granulate are analyzed by the standard addition method. These polymers are used as a catalytic media during crosslinking and further processing.
