WebPolyethylene 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 chemical ... WebThe economics for this process will be compared to a conventional process to produce PET solid-state resins. Other technologies, including Zimmer’s “Direct to Preform” and Uhde Inventa-Fischer’s “Melt to Resin” (MTR), process will be discussed.
