Web1 jan. 2014 · In this work, the influence of thermal crystallinity on the mechanical behavior of PET was observed. Annealed injection molded samples with thermal crystallinity were tested Young’s modulus. Using the two-phase composite approach, mechanical behavior of injection molded semi-crystalline PET samples was modeled based on crystallinity from … WebPolycarbonate – Melting Point. Melting point of Polycarbonate is 297 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs.
