TECADUR PET natural

PET unfilled

Ensinger offers unfilled and unmodified PET polyester as a basic type of PET under the tradename TECADUR PET. Due to its good creep strength, low moisture absorption and outstanding dimensional stability, PET is extremely well suited for applications where complex parts combined with the tightest requirements in dimensional accuracy and surface quality are needed. TECADUR PET also exhibits very good chemical resistance characteristics.
