Polystyrene bead ethanol water
WebAug 7, 2024 · The main technique used for nanomilling API is high energy media milling. This technique relies on milling media—0.2-1 µm beads that are made from ceramics or highly crosslinked polystyrene. The beads shear and collide with the API particles during the milling process, reducing their particle size.
