PRECITE®
E GF 20 8 black (7849)PET GF 20 8
PRECITE® E GF 20 8 black (7849) is a 20% glass fibre reinforced, medium viscosity polyethylene terephthalate (PET) with high stiffness and toughness. Due to its low moisture absorption, this material has very good dimensional stability. This grade corresponds to the European food guideline EU 10/2011 and to the American FDA 21 CFR. Because of its very good surface, it is perfectly suited for kitchen and household appliances.
