Injection of CO₂ into Plastic Extruders Using Teledyne Isco Syringe Pumps
Teledyne Isco Syringe Pumps are excellent for use as CO₂ injection pumps into plastic extruders. These high precision pumps deliver fluids accurately and consis- tently in either constant flow or constant pressure mode. Continuous flow systems are also available.
At the University of Toronto’s Microcellular Plastics Manufacturing Laboratory, research has been ongoing to simulate, understand, and explore solutions for the use of CO₂ in microcellular foamed plastic extrusion and molding applications.
In a typical extruder application, the syringe pump, equipped with a cooling jacket, is connected via a capil- lary tube to the extruder, as shown in Figure 1.
