CNC Machining PEI

PEI (Polyetherimide), commonly known by the ULTEM trade name, is a high-performance thermoplastic known for its excellent heat resistance, high mechanical strength, and stiffness. Its ability to retain mechanical properties at elevated temperatures, along with its electrical insulation and flame resistance, makes CNC-machined PEI suitable for aerospace components, electrical equipment, medical devices, and industrial applications.

Advantages of CNC Machining PEI

Excellent Heat Resistance
High Strength and Stiffness
Good Dimensional Stability
Excellent Electrical Insulation
