Description
PEEK, or Polyetheretherketone, is a high-performance polymer that’s used in a variety of applications:
- Properties: PEEK is known for its high flexural strength and modulus, and its ability to withstand extreme environments. It’s also resistant to moisture and has a wide range of chemical compatibility.
- Uses:Â PEEK is used in structural applications, chemical processing, battery components, water treatment, chromatography, chemical storage, and more.
- Manufacturing: PEEK is made by synthesizing monomers, polymerizing the monomers, and then post-processing the resinÂ
Polyetheretherketone (PEEK) is a thermoplastic material with many properties, including:
- Mechanical strength: PEEK is strong and rigid, with a Young’s modulus of 3.6 GPa and tensile strength of 90–100 MPa. Â
- Dimensional stability:Â PEEK has good dimensional stability and retains its properties in high-temperature and high-pressure environments.
- Chemical resistance: PEEK is resistant to harsh chemicals and hydrolysis from steam, water, and seawater. Â
- Thermal stability: PEEK has a sharp melting point and is resistant to thermal degradation. It can maintain its properties at temperatures up to 338°F (170°C).
- Low moisture absorption: PEEK has low moisture absorption and permeability.
- Low outgassing:Â PEEK has low outgassing and extractables.
- Solid fire performance:Â PEEK has solid fire performance.
- Lower thermal conductivity: PEEK has lower thermal conductivity than most engineering plastics.
PEEK is used in many applications, including:Â
- Aerospace
- Oil and gas
- Food and beverage processing
- Semiconductor
- Electrical connectors
- Sealing system components
- Sensor housings
