Summary

An exploratory investigation was conducted to establish the importance of injection molding conditions for mechanical behavior of two biodegradable thermoplastics. Tensile test results are reported from specimens with 2 mm and 4 mm wall thicknesses, as well as a 2 mm thick specimen with a cold flow weld line. One of the challenges in injection molding with these materials was a limitation to the process window because of narrow margins for melt plasticizing temperatures, pressures and screw rotation rates. The results show that mold filling pressure and melt front speed have a strong effect on tensile behavior, particularly on strain at yield or break.
