Aluminium mould tool for PEEK

PEEK, or poly ether ketone, is a high performance thermoplastic with excellent strength and ductility. It's also FDA compliant for food contact and can be sterilised for medical applications.

Key benefits

  • Good strength and stiffness
  • High ductility
  • Chemically resistant
  • Food safe
