![]() ![]() It requires drying at 150 ☌ for at least four hours, generally 170 ☌, over three to four hours, before processing. PET loses molecular weight when moisture levels exceed the limit the product turns color and becomes brittle. Also, due to their presence, PET has a phospholipid-based structure. Plastic Processingĭue to its lipid-related nature and its hydrophilicity, PET pellets are very sensitive to water at high temperatures. In this situation, the fluidity of the melt is often affected mainly by pressure. As of today, GF-PET is the most popular polymer among customers, which is mainly used in preform injection.Ĭonsequently, the properties of PET in a liquid state are much better, and pressure is more important than temperature in terms of viscosity. Polyethylene terephthalate (PET) is a naturally occurring thermoplastic polymer commonly used in plastic products. This service allows you to make everything you need in one convenient location. Our preforms are available in our facility and can be made in-house or customized to your packaging needs with an individual preform mould crafted from PET.
