Duratron® U1000 are amorphous PEI Polyetherimide shapes that exhibit high strength, dimensional stability, and superior flame and heat resistance. Due to this grade's ability to perform continuously to 340°F / 170°C, Duratron® U1000 PEI is the ideal solution for applications that require consistent dielectric properties over a wide frequency range. Another strength of Duratron® U1000 PEI shapes are their hydrolysis and chemical resistance, enabling them to withstand repeated autoclaving cycles in medical, pharmaceutical, and biotechnology markets.
