Chip-DSC 10 – Polymer sample (PE) – characterization of polymers
Using a DSC for analysing materials is a common technique. In this application, the Chip-DSC was used for measurements of PE granules.
Polyethylene (PE) is the most commonly used polymer because it is easy to manufacture and offers many options. Due to its low weight, its good electrical insulation properties and its excellent chemical resistance, there are thousands of applications, especially in packaging, foils, bottles, etc. PE can be characterized by its crystallinity.
PE could also be defined by its density (PE-LD, PE-LLD or PE-HD). The DSC measurement correlates with its mechanical properties. The higher the density and crystallinity, the higher the peak maximum and the enthalpy. The Onset of TM is at ~ 100 °C for PELD and ~ 130 °C for PEHD.
