What's Possible with Ultem?


Ultem® (polyetherimide) is a semi-transparent, high-strength plastic material that is resistant to hot water and steam and can operate in high-temperature environments. Ultem® has one of the highest dielectric strengths of any thermoplastic material.

Among its advantages:

  • Chemically resistant to chlorine and acidic/caustic cleaning agents.
  • Can be used in temperatures up to 340˚ Fahrenheit.
  • Highly flame-resistant.
  • Highly machinable.

It is because Ultem® resins are so resistant to heat, solvents and flame that Ultem® is the material of choice for a wide variety of items, including:

  • Semiconductor equipment components
  • Electrical insulation parts
  • Electrical connectors
  • Manifolds
  • Scientific equipment parts
  • Medical components
  • Eyeglasses
  • Aircraft instruments

Ultem® has two options:

  • Ultem® 1000 comes is a unreinforced 1000 series plastic that is translucent amber in color and combines exceptional mechanical, thermal and electrical properties.
  • Ultem® 2300 is a glass fiber reinforced plastic in the 2000 series. It has better tensile strength, stiffness and overall dimensional stability.
