Abstract

Evaluation of the thermal properties of a polymer is important for application of hydrogen infrastructure. This study describes the process of measurement of the glass transition temperature using high-pressure differential scanning calorimeter (HP-DSC) in hydrogen condition. Pressure stability of HP-DSC was evaluated up to 8 MPa in hydrogen gas and temperature calibration was carried out in the range from -92℃ to 232℃ using the reference materials. Glass transition temperature of commercial EPDM polymer was measurued at 0.2, 2, 3, 5 MPa in hydrogen condition.
