Preparation and Characterization of Polybutylene Succinate Foams Processed in Supercritical Carbon Dioxide

摘要

Foams have the advantage of low-density, high specific strength and good protection from noise, making them widely applicable to domestic, industrial, and agricultural fields. The most common foam materials are foamed polystyrene (PS), polyurethane (PU), and poly(vinyl chloride) (PVC) etc. but these traditional polymer foams cause serious environmental problems. Therefore, the foaming of Polybutylene succinate(PBS) has become a particularly important project. Because of its environmental friendly nature, However, the PBS has low melt strength that it has been often considered unsuitable for making it into foams.
