Abstract
Thermal insulation materials extend the shelf life of food and reduce energy consumption. Polyurethane (PU) insulation materials are often used to keep food hot and cold. Improving the thermal insulation properties of PU can significantly contribute to energy savings and lower food-related costs in the food and pharmaceutical industries. Polyurethane/expanded graphite (PU/EG) composites were obtained by hot-pressing by adding expanded graphite (EG) to PU foams. Composites with 0.05%, 5%, and 10% EG were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and thermogravimetric analysis (TGA).
