Duratron™ U1000 are amorphous PEI shapes that exhibit high strength, dimensional stability and superior flame and heat resistance. Due to this grade's ability to perform continuously to 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.
