PEEK Polyetheretherketone – Metal Replacement for Critical Applications
Part of the polyaryletherketone (PAEK) group of polymers, polyetheretherketone (PEEK) is a colorless organic thermoplastic polymer that exhibits excellent mechanical and chemical resistance properties, even at high temperatures. It also possesses excellent insulation and electrical resistance properties as well as low moisture and flammability. One of the most versatile materials on the market, PEEK can be injection and compression moulded, extruded, thermoformed, sprayed or machined.
High Performance Properties
PEEK’s outstanding properties include high continuous operating temperature (above 242° C), excellent room temperature properties, very good chemical resistance, inherent V0 to UL 94, good radiation resistance, excellent hydrolysis resistance, extremely good impact strength, minimal creep and an extremely low outgassing rate.
PEEK for Demanding Applications
First produced commercially in the early 1980s, PEEK is now used in demanding engineering applications across a range of sectors, most notably aerospace, automotive and chemicals. Thanks to its strength and durability, it is also increasingly being used as a replacement for metal in the manufacture of products such as aircraft and engine components, medical implants and scientific equipment.

Improved Performance With AKROTEK® PEEK
Drawing on our expertise in polyamides (PA), polyphthalamides (PPA) and polyketones (PK), AKRO-PLASTIC developed AKROTEK® PEEK to combine a range of performance features. In addition to improved performance, it was also important for product development engineers at AKRO-PLASTIC to enable excellent material working properties using methods commonly used in the plastics-processing industry. Alongside conventional glass-fibre- and carbon-fibre-filled compounds, tribologically modified grades are now also available.
AKROTEK® PEEK for Easy Processing
AKROTEK® PEEK can be processed on commercially available injection moulding and extrusion machines. The flow rates achieved thanks to the favourable filler behaviour give development engineers and designers a great deal of freedom when designing components. This also eliminates time-consuming and expensive processing steps as well as providing significant weight savings.
