PEI (Polyetherimide) offers excellent strength and performance up to 170°C, with superior electrical insulation and dielectric properties.

With a UL 94 V-0 rating, it also exhibits exceptional resistance to high-energy radiation such as gamma rays and X-rays.

Features

Duratron PEI is a high-strength, flame-resistant, and heat-resistant amorphous polymer.

It is ideal for applications requiring high strength and consistent dielectric properties across a wide frequency range, even at temperatures up to 170°C.

It has low moisture absorption, excellent resistance to acidic solutions, and can withstand repeated autoclave sterilization cycles.

Duratron U2300 PEI is a glass-reinforced version of Duratron U1000 PEI (with 10%, 20%, and 30% glass fiber options), offering improved rigidity and dimensional stability while retaining most of the base material’s beneficial properties.

Duratron PEI complies with FDA and USP Class VI standards.

Medical-grade Duratron PEI is available in various colors.

Duratron PEI is commonly machined into components for reusable medical devices, analytical instruments, electrical/electronic insulators (including many semiconductor parts), and other parts requiring strength and stiffness at high temperatures.

Applications

Clamp: The material’s high voltage insulation and flame resistance make it suitable for clamps connecting display units and printed circuit boards in aircraft, tanks, and ships. (Previous material: Acetal)

Surgical Probe: Machined from Duratron PEI rod, surgical probes are sterilizable and offer high strength and stiffness. (Previous materials: Acetal, Polysulfone)

Manifold: Machined from Duratron PEI sheet, manifolds used in pharmaceutical process equipment withstand high-temperature chemical solvents and steam sterilization. (Previous material: Aluminum)

Insulator: High-frequency insulators used in microwave communication components can be machined from Duratron PEI. (Previous material: Ceramic)
