WebJun 11, 2024 · The creation of PETG is beneficial due to its ability to stop the crystallization of PET by replacing the ethylene glycol molecules with a larger monomer, Cyclohexanedimethanol. With this change in the molecular chain, PETG molecules don’t collect together as easily (as PET). By lowering the melting points, this hinders … WebThe crystallization peak of PET begins to weaken when the thermal treatment temperature is below 255 °C, indicating that the majority of PET crystals are un-melted with self-nucleation and annealing taking place … photo books a5
