Influence of thermo‐oxidative aging on the mechanical properties of the bead foams made of polycarbonate and polypropylene

Abstract Bead foams made from standard polymers such as expanded polystyrene (EPS) or polypropylene (EPP) are widely used in everyday products. In order to expand the application window of bead foams, industry, automotive industry among others, is striving for higher‐performance materials create a lightweight material high‐temperature applications. New polycarbonate (EPC) emerging offer wider range solutions, with thermo‐mechanical properties constantly improving. EPC has excellent mechanical properties, which been shown our previous work. To fully understand capabilities applications, it important know what happens when exposed conditions, that lead aging. Morphological studies, well characterizations help determine compared EPP. Since thermo‐oxidative aging thermoplastic almost unexplored, especially field this research represents an contribution understanding behavior and development. Time‐consuming tests were able confirm not only very thermally stable material, but also provide reasonable performance after aging,
