PE materials such as high-density polyethylene (HDPE) are often used for the production of packaging materials and foils. Differential scanning calorimetry is often used to characterize the melting behavior of such materials, but the DSC 200 F3 Maia^® can do even more. Due to its excellent low-temperature performance and outstanding sensitivity, the system also allows the detection of the glass transition (at –119.9°C). This extremely weak step in the DSC-curve is presented in the embedded picture in more detail.
