Abstract of presentation
Thermoforming processes and applications in Polyetheretherketone
Author – Mike Percy, Films Global Technology Manager, Victrex plc.
Abstract – Polyetheretherketone (PEEK) resin has been produced in commercial
quantities for over 20 years, and while it is used widely in highly demanding injection
moulded and machined applications, its use as a film in thermoforming applications is only now being discovered. As performance demands for higher temperatures &
increased performance push designers further we are seeing an increased need for PEEK in film format to be used in thermoforming applications. This has co-incided with the wider availability of PEEK films and sheets in the marketplace during the last 2 years. This paper will review some of the basic background of PEEK film properties, and in particular the two crystalline forms that are commercially available. This will include the typical thermoforming processing conditions and equipment that have been used to produce a range of thermoformed parts from thicknesses of 6 microns up to as much as 1000 microns. Some details of current application areas for thermoformed PEEK parts will be included in the paper.
