PRECITE®
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.

Processing information
The values mentioned are recommendations. We only recommend desiccant / dry air dryers or vacuum dryers. Too long a drying time and the resulting residual moisture content below the lower limit can lead to filling problems and surface defects. The specified drying time refers to closed and undamaged bagged material. When processing from previously opened bags or from octabins with polyolefin inliners, a longer drying time may be necessary. It is recommended to check the residual moisture content after the drying process.
