Web24. feb 2024 · PETG polymers with low crystallization rates are the ideal choice for thick-walled transparent packaging. The low crystallization rate is the result of the inhomogeneity of the molecular structure, which affects the folding of long molecules into thermodynamically stable structures. Web12. aug 2024 · Polyethylene terephthalate glycol, known as PETG or PET-G, is a thermoplastic polyester that delivers significant chemical resistance, durability, and formability for manufacturing. PETG is an adaptation of PET (Polyethylene terephthalate) where the ‘G’ stands for glycol, which is added at a molecular level to offer different …
