Ultem 1000

Characteristics of Ultem 1000


Polyetherimide (PEI) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Ultem 1000 combines excellent machinability and provides a cost savings benefit over PES, PEEK, and Kapton in high heat applications (continuous use to 340 degrees F).

Ultem Characteristics/Properties:

Ultem is a family of PEI products manufactured by SABIC as a result of acquiring the General Electric Plastics Division in 2007.

Ultem resins are used in medical and chemical instrumentation due to their heat resistance, solvent resistance and flame resistance. Ultem 1000 (standard, unfilled polyetherimide) has a high dielectric strength, natural flame resistance, and extremely low smoke generation. Ultem has high mechanical properties and performs in continuous use to 340°F (170°C). Ultem 1000 has a thermal conductivity of 0.122 W/(m*K).

The glass transition temperature of PEI is 216 °C. Its amorphous density at 25 °C is 1.27 g/cc. It is prone to stress cracking in chlorinated solvents.UL V-0 Rated, low dissipation factor and transparent.
