GEWOPEI 1000 / 1.75mm (Ultem 1000, Polyetherimid, PEI)

GEWOPEI is an amorphous high-performance plastic based on polyetherimide (PEI). Its most important advantages are an outstanding tensile strength combined with a very high flexural modulus as well as a very good combustion behaviour: PEI is low fuming and achieves the highest flamability ratings according to all common standards.

Advantages of PEI:


  • highest tensile strength at room temperature of all unmodified high-performance plastics
  • very high mechanical strength and rigidity
  • high heat deflection temperature
  • low creep tendency
  • resistance to various chemicals
  • very high flame resistance
  • physiologically harmless

PEI - application fields:

  • electronics and electrical appliance
  • aerospace
  • medical technology
