About PEI (ULTEM™)

PEI (Polyetherimide), also known as ULTEM™, Duratron® or Torlon®, is an amorphous engineering thermoplastic offering exceptional mechanical, thermal and electrical properties. It can be easily machined with conventional metalworking tools, and can be painted, hot stamped, printed or metallized.

PEI is dimensionally stable and offers good hydrolytic stability. It combines high heat resistance, excellent electrical properties, and inherent UV and flame resistance along with low smoke generation. However, it has very limited resistance to chemicals. It is transparent to visible infrared and microwave radiation.
