PLA is harder than ABS, melts at a lower temperature (around  180Â°C to 220Â°C), and has a glass transition temperature between 60-65 Â°C, so is potentially a very useful material. It does exhibit higher friction than ABS however which can make it difficult to extrude and more susceptible to extruder jams.
Thermal properties. The melting point of polypropylene occurs at a range, so a melting point is determined by finding the highest temperature of a differential scanning calorimetry chart. Perfectly isotactic PP has a melting point of 171 Â°C (340 Â°F). Commercial isotactic PP has a melting point that ranges from 160 to 166 Â°C (320 to 331 Â°F), depending on atactic material and crystallinity. Syndiotactic PP with a crystallinity of 30% has a melting point of 130 Â°C (266 Â°F). Below 0 Â°C, PP becomes brittle.
