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® 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® 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.

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.
