TECAPEI natural

unfilled PEI

TECAPEI natural (PEI) is an unreinforced polyetherimide, suitable for contact with foods, that exhibits high mechanical strength and rigidity. The characteristic profile includes very good hydrolysis resistance, and dimensional stability, combined with a relatively high long term service temperature.
