is polyester a plastic
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.
