PEI (Ultem) Machining Services
High-performance PEI parts from China’s leading manufacturer
What is PEI (Ultem)?
PEI (Polyetherimide), commonly known by the trade name Ultem, is an ultra-high-performance amorphous thermoplastic that offers exceptional mechanical, thermal, and chemical resistance properties. This premium engineering material maintains its strength and dimensional stability at elevated temperatures where most plastics would fail.
With outstanding flame resistance, low smoke generation, and excellent electrical insulation properties, PEI/Ultem has become the material of choice for the most demanding applications in aerospace, medical, automotive, and electronics industries.
Its inherent high strength, stiffness, and heat resistance combined with biocompatibility and sterilization capability make it ideal for applications requiring both performance and safety.
Key Features
- Continuous use up to 170°C
- Excellent flame resistance (UL94 V-0)
- Superior mechanical strength
- Biocompatible & sterilizable
- Low outgassing
