Polyetherimide, also known as Ultem, is an amorphous material with extremely high heat resistance compared to other plastics. Due to its rigidity and high heat performance, polyetherimide is most commonly used in medical devices, electronics, and industrial plastic parts.

Advantages of Polyetherimide:

  1. Rigidity – hard plastic useful for high-impact industrial applications
  2. Heat Resistance – doesn’t melt or warp under high temperatures
  3. High Tensile Strength – resists cracking or breaking in hard environmental conditions
  4. Flame Resistance – isn’t flammable and generates low smoke
