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 ... WebPET, or Polyethylene terephthalate, is a combination of two monomers. PETG is of the same hemical composition as PET but with the addition of glycol. With just this one addition, the chemical composition is completely changed, creating a whole new plastic. The addition of glycol to create PETG removes the hazing effect seen during heating and ...
