PEKK - high performance engineering thermoplastic
PEKK (Polyetherketoneketone), not to be confused with the more common PEEK (Polyetheretherketone), is one of a large family of polyketones. It has a higher use temperature and radiation resistance comparable to that of PEEK. However, the trade-off is that processing temperatures are marginally higher.
PEKK is a high performance thermoplastic material which has arguably the highest glass transition temperature (Tg) of all commercially available polyketones. Its ability to retain a high degree of chemical resistance and physical properties up to its Tg of 162°C (semi-crystalline grade) makes PEKK an ideal choice for many high temperature engineering applications.
• High continuous operating temperature
• Good wear resistance
• Excellent chemical resistance
• Resistance to radiation
• Inherently flame retardant (UL94 V-0 rated)
• Dimensionally stable
• High purity
This excellent combination of properties makes PEKK ideal for use in a broad range of industrial sectors:
• Aerospace
• Oil & gas
• Electronics
• Chemical process
• Compressors
One interesting new application is its possible use in fuel cell technology, where it can be used a proton exchange membrane.
PEKK is available from Goodfellow Cambridge as a granule for injection moulding.
