Determining Thermal Properties of Polyurethane by Solving the Heat Equation and IR Imaging
All materials have different and unique thermal properties that determine how the temperature changes when a material is subjected to a temperature difference. This study was intended to investigate the thermal properties of a polymer called Polyurethane, focusing on anti-seepage and anti-abrasion p...

All materials have different and unique thermal properties that determine how the temperature changes when a material is subjected to a temperature difference.
