PET – Polyethylene Terepthalate
PET polyesters are semi-crystalline. They are versatile materials with a good range of properties. They have excellent electrical properties and are abrasion resistant. PET has not been as extensively compounded as PBT because it is more difficult to process. PET has a higher modulus than PBT. Like PBT, PET is very anisotropic in shrink, therefore it is difficult to mold to extremely close tolerances.
Applications: Reusable bottles, Pacifiers, Sippy cups, Bottle sterilizer lids, Medical devices, Housewares.
