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.

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.

The stock shape is also pre-assessed for biocompatibility for up to 24 hours contact with body and tissue according to USP VI and ISO 10993. Some color variations are also pre-assessed for use in wetted contact applications in bioprocessing.

Combining biocompatibility with peak performance, Duratron® LSG PEI exhibits outstanding mechanical, thermal, electrical properties, as well as very good resistance to hydrolysis and chemicals.

Duratron® LSG PEI components are also sterilizable by means of steam (autoclave), dry heat, EtO (Ethylene Oxide), plasma, and gamma- & X-ray irradiation. Due to these properties, Duratron® LSG PEI is an excellent candidate for applications in the medical and bioprocessing fields such as trial implants and radiotherapy applicators. 

Duratron® U2100 PEI Polyetherimide shapes are 10% glass-reinforced, giving them greater rigidity and dimensional stability over Duratron® U1000, as well as a low coefficient of linear thermal expansion. With an excellent strength-to-weight ratio and high tensile strength, this grade is ideal for 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 (CLTE), 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.
