Ultem®

  Trade Name
  • Tempalux®
Utem PEI PolyetherimideUltem 1000 polythermide® is an amorphous polymer offering high strength and excellent resistance to flame and heat. Since Ultem 1000 performs continuously to 340°F (170°C), it is ideal for high strength/high heat applications, and those applications requiring consistent dielectric properties over a wide frequency range. It is resistant to hydrolysis, highly resistant to acidic solutions, and capable of withstanding repeated autoclaving cycles.
Some key attributes of Ultem 1000®:
  • High strength
  • Performs continuously to 340°F (170°C)
  • High dielectric strength
  • UL94-V-0 rated
  • High strength and heat resistant
  • Autoclavable

 

Applications:
  • Structural Probes
  • Surgical Probes
  • Manifolds Pharmaceutical Process Equipment
  • High Frequency Insulators used in Microwave Communications
  • Semiconductor
  • Medical
  • Pump Housings
  • Wafer Processing

 

Size Offering:

Rod - Diameters are available from 1/8" to 8." Larger sizes are available on a quote only basis.

Sheet - Thickness' available from 1/16" to 4." Larger sizes are available on a quote only basis.

Sheet Size - Most sizes are available from 12" x 12" to 24" x 48."
