Ultem PEI machining parts
Ultem PEI machining parts description
For machined parts requiring added strength, engineers turn to Ultem®. This high-performance thermoplastic is considered one of the best for exhibiting excellent strength and stiffness. Ultem® also maintains great dimensional stability at high temperatures (200°C).
Engineers turn to this material when they need parts machined for demanding applications in the Aerospace industry for aircraft and spacecraft and in Medical industry applications requiring repeated sterilization cycles.
As is the case with many high-performing plastics, understanding the machining characteristics of Ultem® is critical to producing a precision part. Many companies machine Ultem, but it’s critical to work with one that knows how to manage stresses in the material to achieve complex tight tolerance parts.
