PET material (chemically known as polyethylene terephthalate) is a polyester with a relatively high density and is manufactured by Ensinger in standard stock shapes for machining. PET is available either as an amorphous or semi crystalline thermoplastic. The characteristics of the amorphous type of PET polymer are high transparency, but lower mechanical properties such as tensile strength, as well as substantially lower sliding characteristics. However, Ensinger does not manufacture the PET material which ends up mostly in bottles or packaging. The typical properties of the semi crystalline terephthalate that Ensinger does manufacture are hardness, rigidity, strength, outstanding sliding behavior and low wear (compared to POM in damp or dry environments). This material has long been referred to as PET-P plastic, but this is an outdated form of reference for PET material today.
Due to its good creep strength, low moisture absorption and outstanding dimensional stability, PET plastic material is extremely well suited for applications where complex parts and the highest requirements regarding dimensional accuracy and surface quality are needed. The thermal properties of PET support a good temperature stability as well as dimensional stability.
