CNC Machining PI (Polyimide)

Polyimide (PI, commonly known as Vespel®) is one of the highest‑performance engineering plastics available. It delivers exceptional continuous high‑temperature resistance up to 260‑310°C, outstanding dimensional stability, superior electrical insulation, low outgassing performance, excellent radiation resistance and inherent flame retardancy. It is widely used for semiconductor tooling, aerospace auxiliary components, vacuum‑chamber parts, high‑temperature bearings and precision insulating assemblies.
