PEI

Overview

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.
