Hot Melt Extrusion in the Pharmaceutical and Food Industries

July 04, 2019 / SALLY ROBERTSON

Hot melt extrusion is a manufacturing technique that was originally established in the early 1930s for use in the plastics and food industries but is now gaining popularity in the pharmaceutical industry as well. Around half of all plastics products are made using hot melt extrusion, which is the process of producing a new material (i.e. an extrudate) by forcing a melted polymer through an orifice, as heat and pressure are applied.
