Preliminary

E GF 50 natural (7300)PET GF50

PRECITE® E GF 50 natural (7300) is a 50% glass fibre reinforced, medium viscous polyethylene terephthalate (PET) with very high stiffness and toughness even at elevated temperatures. 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, where a very good surface finish is required.
