PPS filled with 40% glass fibre

TECATRON GF40 black is a 40% glass fibre reinforced PPS. Because of the high level of glass fibre reinforcement, TECATRON GF40 black demonstrates excellent rigidity and very high strength at high temperatures compared to unmodified PPS (TECATRON natural). High thermal stability, high dimensional stability, very good chemical resistance, good electrical and thermal insulation and good resistance to sterilization rounds out the property profile of this modified PPS. These material properties make glass filled PPS suitable for use in parts that are exposed to high static loads over long periods in high temperature conditions. However, the inherant chemical structure along with the addition of glass fibres tends to create toughness issues with this material. As glass fibres tend in some cases to have a marked abrasive effect on mating surfaces, this PPS composite may be less suitable for sliding applications.
