What is PET Polyethylene Terephthalate?

PET Polyethylene Terephthalate is a robust engineering plastic renowned for its exceptional mechanical strength, rigidity, and resistance to wear. This polyester material is a popular choice for applications requiring dimensional stability, high pressure resistance, and low friction. Its low moisture absorption ensures reliable performance and accuracy during manufacturing and in end-use environments.

Compared to alternatives like POM (polyacetal) or PA (nylon), PET Polyethylene Terephthalate stands out with its ability to withstand higher operating temperatures and its superior resistance to acids. While not impact-resistant at low temperatures and unsuitable for hot water or steam (above +60°C), PET excels in dry and chemically stable environments, making it indispensable in various industries.
