View Typical Property Values

ULTEM® is an amorphous thermoplastic polyetherimide (PIE) 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 dimensional stability.

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
High mechanical strength
High dielectric strength and stability
(The high dielectric strength and constant values of ULTEM® make it an excellent electrical insulator UL 94 V.O)
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.
Natural Grade is FDS, NSF, and USP Class VI

ULTEM® has many applications in medical, electronic/electrical, microwave, automotive, and aircraft industries.
