PRECITE®
PET GF 40
PRECITE® E GF 40 natural (7304) is a 40% glass fibre reinforced, medium viscous polyethylene terephthalate (PET) with 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 sureface finish is required.
