    In the specification of the Polyethylene Terephthalate (PET), Intrinsic Viscosity (I.V.) is a measure of the polymer’s molecular weight and thus, an indicator of its physical properties and processing characteristics. The I.V. value of PET can affect its strength, toughness, clarity, and how it processes in various applications such as fiber, bottle, or film production…
