Abstract Polylactide (PLA) bead foams show a high potential regarding their applicability in packaging or consumer products. Concerning the comparable properties of PLA to Polystyrene (PS) and the good CO2 footprint it represents
a potential alternative to petroleum-based polymer foams. However, foaming of PLA is challenging, due to its low
melt strength, therefore chemical modifiers are often used. Concerning the bead foam technology regarding PLA,
the available literature is limited so far. Within this study, the bead foaming behavior of neat and modified amorphous PLA was investigated. The material was modified by talc and an epoxy-based chain extender. These compounds have… More >
