This polymer is derived from renewable sources and is biodegradable. It can easily be melted and shaped without losing its mechanical properties. It has a melting point of 145 – 160°C. Its mechanical properties lie between those of polystyrene and PET. However, its low glass transition temperature makes it unsuitable for use in holding hot liquid. It is commonly used in plastic films, bottles, and medical devices.
Low glass transition temperature • Biocompatible • High tensile strength
