PEEK Ultrafine Powder
PEEK Ultrafine Powder is a high-end grade produced through jet-milling, classification and surface treatment, reducing PEEK to a particle size range of 0.5 – 10 μm. With a high specific surface area, narrow PSD and very low metal impurity content, it is engineered for high-value applications including premium functional coatings, SLS 3D printing and specialty functional fillers.
