Preparation of Poly(Butylene succinate)(PBS) Foaming Materials

Abstract:

Poly(butylene succinate)(PBS) is a kind of biodegradable materials. In this paper PBS foaming materials is prepared by physical foaming method of one-step compression molding. The influences of blowing agent and nucleating agent, the foaming temperature and foaming time on the cellular morphology of PBS foaming materials have been studied. The results showed that when the foaming temperature was 160°C，the blowing agent content was 5 parts, the foaming pressure was higher than 10 MPa, and the foaming time was 20 minutes with nucleating agent addition, the cellular morphology and mechanical properties of the foaming materials were better. The results showed that the foaming technology influenced greatly on the properties of foam of PBS materials. The expansion ratio had a small drop when the temperature increased. The addition of nucleator talc and foaming aids urea increased first then decreased the expansion ratio of the PBS foaming materials.
