ULTEM® is an amorphous thermoplastic polyetherimide (PEI) material which combines exceptional mechanical, thermal, and electrical properties. Natural ULTEM® 1000 (unreinforced) is a translucent amber material. The addition of glass fiber reinforcement to the basic ULTEM®, coupled with Ensinger?s proprietary extrusion techniques, provides the ULTEM® with both greater tensile strength and rigidity while at the same time improving
- Excellent mechanical strength
ULTEM® exhibits high tensile strength at room temperature and retains a significant portion of this strength at elevated temperatures.
Glass fibers further increase high-temperature strength.
- Outstanding heat resistance
ULTEM® retains its physical properties at elevated temperatures.
- Exceptional resistance to environmental forces
Environmental characteristics of ULTEM® include it?s stress resistance.
- Inherent flame resistance with low smoke evolution
Tested internally to UL 94 V-O.
- High mechanical strength
- High dielectric strength and stability
The high dielectric strength and constant values of ULTEM® make it an excellent electrical insulator.
- Low dissipation factor over a wide range of frequencies
- Excellent machinability and finishing characteristics
ULTEM® can be easily machined with conventional metalworking tools, painted, hot stamped, printed, or metallized.
ULTEM® has many applications in medical, electronic/electrical, microwave, automotive, and aircraft industries.
