This is a special 30% glass fiber reinforced PEI, manufactured by Ensinger under the tradename TECAPEI GF30 natural. In comparison to unfilled PEI (TECAPEI natural), PEI GF30 demonstrates high rigidity, very high mechanical strength, as well as extremely good dimensional stability, and good resistance to high energy radiation. These properties make PEI with 30% glass fibers suitable for use in parts that are exposed to high static loads over long periods in high temperature conditions.
