High Performance > 300°F | Polyetherimide (Ultem®)

TECAPEI GF30

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.
  • Resin used in natural grade are FDA, and

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