Polyester Plastics - PET

PET is a polyester plastic with excellent wear resistance, a low coefficient of friction and good chemical resistance. Its dimensional stability, combined with low moisture absorption, allows PET polyester plastics to be machined into precise, high-tolerance components. PET is both FDA and 3A-Dairy compliant, making it ideal for food applications.

PET has good mechanical properties, and it works well for high load and wear conditions. PET can be formulated with additional lubricants to increase its wear characteristics without changing the basic attributes of the material.
