A High-end Plastic
PEEK stands for polyetheretherketone and is an extremely high temperature-resistant thermoplastic material with a melting point of 335°C. It is resistant to almost all organic and inorganic chemicals.
However, it reacts to UV radiation, concentrated nitric acid, some halogenated hydrocarbons, and generally acidic oxidizing conditions.
Because of its special property profile, PEEK is a particularly suitable material for demanding applications in the aerospace industry, the automotive field, and electronics and semiconductor technology. As the material is biologically compatible, repeatedly sterilizable, and radiolucent, it also has numerous applications in medical engineering. It is also used for parts that come into contact with products in the pharmaceutical and food industries. In the chemical industry, PEEK can be found in applications requiring particularly high mechanical, thermal, and chemical resistance.
