Polyetheretherketone (PEEK) is a special engineering plastic. It was first developed by Imperial Chemical Industries (UK) in 1978. In the field of engineering plastics, PEEK is at the very top of the pyramid. It has comprehensive and outstanding performance. It can rival ordinary metals and outperforms most plastics. When compared with metals, PEEK stands out with excellent properties.
It has become a key material for the lightweight concept of “replacing steel with plastic.” PEEK Micropowder is created through advanced grinding processes, where technologies such as the jet mill for Polyetheretherketone play a crucial role. By reducing PEEK resin into ultrafine, uniform particles, jet milling ensures the powder retains PEEK’s superior characteristics—high-temperature resistance, chemical corrosion resistance, mechanical strength, and excellent biocompatibility. This makes PEEK micropowder an ideal choice for aerospace, medical, electronics, and other high-end applications.

A critical Role of Jet Mill for polyetheretherketone (PEEK) Preparation
1. Raw material refinement:
Jet milling reduces PEEK powder to D50 < 10 μm. This improves fiber impregnation efficiency during melt infiltration. Studies show that uniform particle distribution reduces composite porosity by over 30%.
2. Nanocomposite modification:
Jet milling disperses nano-reinforcements (such as nanodiamonds) at the submicron level. This provides super-lubrication with friction coefficients as low as 0.03. Such materials are ideal for precision medical devices like interventional catheters.
3. Process optimization:
- Temperature-pressure synergy: Jet mill pretreatment combined with hot pressing lowers forming temperatures by 20–30°C (down to ~350°C).
This reduces resin thermal degradation risks. - Functional modification: Jet milling grafting introduces active groups (e.g., heparin molecules) onto PEEK surfaces. This imparts anticoagulant properties and reduces thrombosis risk by 40%.
