Benefits of PEEK materials
PEEK plastics (polyetheretherketone) are some of the most chemically inert, thermally stable, and mechanically robust parts you can find.
The inherent chemical and structural stability of PEEK parts comes from the rigid aromatic backbone of the polymer, which is ideal for high-performance applications.
PEEK parts offer you:
-
High glass transition temperatures up to 143 °C
-
Tensile strength of 90 – 100 MPa
-
Thermally stable up to 260 ºC
-
High melting point at 341 °C
Because of the robust chemical, mechanical, and thermal properties, industries like automotive, aerospace, medical device, and electrical use PEEK parts to drive continual performance under extreme heat and pressures.
