AKU®-TEC PEI SOLID RODS or ROUND BARS

Polyetherimide

PEI for short, is a high-performance thermoplastic from the polyaryletherimide family.
It is characterized by a unique combination of properties. 

Properties of PEI:

• High temperature resistance:
  PEI retains its mechanical properties at high temperatures, typically up to around 180°C, and even up to higher temperatures in the short term.

• Excellent mechanical strength:
  PEI has a high tensile strength and rigidity, which makes it suitable for structural applications and components with high loads.

• Chemical resistance:
  PEI is resistant to many chemicals, including acids, bases and various solvents.

• Good electrical insulation:
  PEI has excellent dielectric properties and is therefore often used in the electrical industry for insulators and other electrical components.

• Flame retardant:
  PEI can have flame-retardant properties and therefore often meets fire protection standards.

• Good dimensional stability:
  PEI retains its shape and dimensions well even at different temperatures, which makes it suitable for applications with tight tolerances.

Applications of PEI:

PEI is used in various industries, including:

• electronics industry:
  Enclosures for electrical and electronic devices, connectors, insulators and circuit breakers.

• Medical technology:
  Sterilizable components, housings for medical devices due to its heat resistance and sterilizability.

• Aerospace:
  components for aircraft and spacecraft due to its high temperature resistance and strength.

• Automotive industry:
  Parts that are exposed to high temperatures and mechanical loads, such as in the engine compartment.

• Industrial applications:
  Pump and valve components, components for mechanical engineering, applications in corrosive environments.

PEI is widely used in demanding environments due to its thermal stability, mechanical strength and chemical resistance.
