Poly (butylene succinate) (PBS), as a fully biodegradable thermoplastic, have developed rapidly due to its integrated performance and processibility. The CaCO3 as a reinforcing component, and AHP, APP and CaHP as a flame-retardant component were separately incorporated into PBS matrix. A series of PBS-based composites were fabricated via melting blending using internal mixer followed by injection molding. The results show that the different filling ratio has a certain influence on the mechanical properties of the composites. When the filling am...
