PEEK Coarse Powder
PEEK Coarse Powder, also referred to as virgin or base powder, is produced by polymerizing PEEK resin, extruding it into pellets, and subsequently grinding and classifying to a particle size range of 200 – 1000 μm. It is the highest-volume and most widely used grade in the PEEK powder family, suitable for direct injection, compression and extrusion molding, and is also the feedstock for further grinding into fine and ultrafine grades.
