Duratron® U1000 PEI Polyetherimide shapes 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.

Duratron® U2100 PEI Polyetherimide shapes are 10% glass-reinforced, giving them great rigidity and dimensional stability, and a low Coefficient of Linear Thermal Expansion. With an excellent strength-to-weight ratio and tensile strength, this grade is also ideal for for semiconductor and electronics applications.

Duratron® U2200 PEI Polyetherimide shapes are 20% glass-reinforced, giving them exceptional rigidity and dimensional stability, high temperature resistance, and a low Coefficient of Linear Thermal Expansion. With an exceptional strength-to-weight ratio and increased tensile strength, this grade is also a great electrical insulator for semiconductor and electronics applications.

Duratron® U2300 PEI is a flame resistant Polyetherimide that is 30% glass-reinforced, allowing this grade to exhibit the highest rigidity, strength, dimensional stability, and heat resistance of all Duratron® PEI shapes. Possessing the lowest Coefficient of Linear Thermal Expansion, and superior strength-to-weight ratio and tensile strength, this grade is favored as a solution for reusable medical devices, analytical instruments, electrical insulators and semiconductor process components, and structural components that require high strength and rigidity at elevated temperatures.
