The application of Differential Scanning Calorimetry (DSC) for material analysis is a widely employed technique. In this particular case, Chip-DSC was utilized for measuring PE (Polyethylene) granules.

Polyethylene (PE) stands out as the most prevalent polymer due to its ease of manufacturing and diverse applications. Its low weight, excellent electrical insulation properties, and impressive chemical resistance make it highly versatile, finding extensive use in packaging, films, bottles, and more. The crystallinity of PE is a defining characteristic.

PE can be categorized based on its density (PE-LD, PE-LLD, or PE-HD), and DSC measurements are correlated with its mechanical properties. The peak maximum and enthalpy increase with higher density and crystallinity. The Onset of TM (melting temperature) is approximately 100 °C for PELD and around 130 °C for PEHD.
