dc.description.abstractIn this study, we analyse the extrusion foaming capabilities of polyhydroxyalkanoates (PHAs) with endothermic chemical blowing agents (CBAs) based on sodium bicarbonate and citric acid. An epoxy functionalized chain extender (CE) is used to improve the melt strength. The effects of CE addition and cooling system (water and air) are evaluated by means of cellular structure characterisation and mechanical properties analysis of PHA foams obtained. The higher density reduction has been obtained with addition of 1% of CE and 3-4% of CBA. The use of the CE has produced higher pores in the cellular structure regardless the cooling system chosen, giving worse cellular structures. However, best mechanical results were performed by air cooled samples with 1 wt.% of CE
