  • Production of polymer particles below 5 m by wet grinding

    Highlights Polymer particles below 5 m are produced by wet grinding at reduced temperatures. The approach is even applicable to PEEK with high fracture toughness. Higher stirrer speed and lower temperature reduces final particle size and enhances kinetics. Appropriate choice of solvent viscosity avoids viscous dampening of bead motion.
