PEEK/PAEK/PEKK

PEEK (chemically known as polyetheretherketone) is a unique semi-crystalline engineering thermoplastic that also offers excellent chemical compatibility.

Parts made of PEEK polymer high-temperature plastic can also be used at temperatures up to 260 °C (480 °F) and have a melting point of approximately 341 °C (646 °F). PEEK plastic is often used in hot water or steam environments because it maintains high levels of physical properties such as flexural and tensile strength despite the harsh environment.​

PEEK offers wear, moisture and chemical resistance, as well as exceptional strength, dimensional stability and rigidity. Due to its high performance, PEEK is used in many demanding environments in the medical, nuclear, chemical processing and aerospace industries. The price level of PEEK is at the upper end of all the thermoplastics.

PAEK (polyaryletherketone) and PEKK (polyetherketoneketone) belong to the same family and have similar, albeit lower, performance compared to PEEK.

The properties offered by PEEK (/PEAK/PEKK) are:

• Excellent strength-to-weight ratio
• Creep Resistance
• Head-Wearing
• Withstand very high temperatures
• Radiation and chemical resistant
• Low water uptake
