What Is PEI?
PEI is a high-performance thermoplastic engineered for strength, heat resistance, and electrical performance in demanding environments. It is composed of polyetherimide resin, resulting in a material with excellent mechanical properties and inherent flame resistance. This structure enables consistent performance under thermal and mechanical stress. PEI offers high dielectric strength, low moisture absorption, and strong dimensional stability, making it suitable for precision components and electrical applications. It performs reliably at temperatures up to 170°C (338°F) while maintaining structural integrity. This material is a dependable choice for applications that require high temperature performance, strength, and reliable electrical insulation.
