GEHR Plastics PEI Polyetherimide
Categories: Polymer; Thermoplastic; Polyetherimide (PEI)

Material Notes: Polyetherimide has a high mechanical strength in connection with a good chemical and heat resistance, good dimensional stability and creep resistance. Its unique torque strength permits the economical substitution of machining fabricated small parts from steel.

Properties

  • very high strength and rigidity
  • high torque strength and hardness
  • high thermostability
  • high weather resistance
  • high radiation resistance
  • self-extinguishing
  • limited resistance to stress cracks
Applications include parts for electrical engineering, food industry, and aircraft construction.
