PET Polyester
PET (polyethylene terephthalate) is a semi-crystalline thermoplastic with high stiffness and tensile strength, and dimensional stability comparable to acetal (POM). It combines very low moisture absorption, a low coefficient of friction, and excellent resistance to abrasion and tearing, with low creep and easy machining. It is ideal for precision components under heavy loads and abrasive conditions; available in FDA-compliant grades for the food industry.

Note: Semicrystalline PET in black and white, with FDA-compliant grades available on request. Values are for reference and may vary by grade. In engineering plastics, composition is identified by the base polymer, the process and its modifications, not by chemical percentages as with steels. The information and values in this data sheet are provided for reference only and may vary depending on manufacturing and application conditions. They do not constitute guaranteed specifications, so use and interpretation of this data is the user's responsibility.
