Material hierarchy: Polymer - Engineering Thermoplastic
These materials are crystalline polymers of aromatic ketones that exhibit exceptional high-temperature performance.
Polyketones can be processed by conventional methods, with predrying a requirement. Injection-molding melt temperatures range from 710 to 770°F, and mold temperature have to be over 300°F. The materials also can be extruded for wire coating and for slot cast films. Powdered resin is supplied for rotational molding and for coating.
Glass- and carbon-fiber-reinforced polyketone compounds are standard, and PEEK also is combined with continuous carbon fiber to produce a thermoplastic prepreg for compression molding.
Because of their high price, uses for polyketones generally are in the highest-performance applications such as metal replacement parts for aircraft and aerospace structures, electrical power plants, printed circuits, oven parts, and industrial filters.
