PRECITE®

Preliminary

E 3 natural (8457)PET

PRECITE® E 3 natural (8457) is an unreinforced, nucleated and medium viscosity polyethylene terephthalate (PET). Due to its very good flowability, an improved surface quality is achieved. This type is characterised by faster crystallisation compared to a standard PET. Due to its low moisture absorption, this material is particularly dimensionally stable and therefore perfectly suitable for precision parts in the automotive, E&E and household goods industries.
