About PET plastic

PET plastic is a short name for Polyethylene Terephthalate. Although it has been called PET-P plastic for a long time, it is an outdated name. Nowadays, most people call it PET material.

PET plastic is a semi-crystalline engineering thermoplastic polyester. Its density is 1.38 g/cm³, which is relatively higher than most plastics. Compared to POM plastic, PET plastic offers excellent dimensional stability, low moisture absorption, and high strength. Therefore, it suits complex parts with high dimensional accuracy and surface quality requirements.

If a solid lubricant is inside, PET plastic can offer high wear resistance and a low coefficient of friction. It also offers outstanding thermal properties, such as good temperature and dimensional stability.
