What is PET Thermoplastic Materials?
Polyethylene terephthalate, or PET, is a thermoplastic resin, which derives from the polyester family and is commonly used in food and beverage applications. Depending on processing, PET can be semi-rigid or rigid, or amorphous (transparent) or semi-crystalline (opaque and white). PET can be synthesized through a transesterification reaction between ethylene glycol and dimethyl terephthalate. In some cases, PET plastic can be modified for more desirable properties. For example, when glass particles or fibers are integrated, PET becomes significantly stiffer and more durable under various conditions. This glass-filled thermoplastic, semi-crystalline formulation is developed by DuPont and sold under the name Rynite®. PET Plastic Properties Although PET in its natural state is colorless and transparent, it can be reinforced to meet customer s color requirements. In addition, certain reinforcements make PET plastic a good gas and fair moisture barrier, as well as a good barrier to alcohol
