PEEK in Aerospace: A High-Performance Polymer for Flight-Critical Components
September 16, 2026
PEEK for Flight-Critical Components PEEK (polyetheretherketone) is a semi-crystalline thermoplastic engineered for environments that destroy conventional polymers and many metals. For aerospace applications, PEEK delivers a combination of properties that no other engineering plastic matches: continuous service to 500°F (260°C), inherent flame retardancy that supports FAR 25.853 compliance, and a strength-to-weight ratio that makes it…
