Processing TPU via Twin screw extrusion

Twin screw extruders (TSEs) are used to process virtually every type of plastic that is used today. The goal of this chapter is to define how twin screw extrusion (TSEs) can be used to process thermoplastic polyurethane (TPU) formulations that contain additive and fillers into pellets and shapes. Some simple formulas are interspersed with the text to provide insight into how TSEs are designed and the advantages of using TSEs for the synthesis, processing, and compounding of thermoplastic urethanes.

In addition to basic TSE theory, compounding techniques and for wide ranging polyurethane applications, examples of these specialty TPU systems are described:

  • Reactive system with monomer injection and underwater pelletizer
  • Direct sheet extrusion with high radiopaque filler %
  • Supercritical CO2 injection for foamed product

Editor's note: Reference Szycher's Handbook of Polyurethanes, 2nd Edition, A practical handbook, rather than merely a chemistry reference, offers an easy-to-follow compilation of crucial new information on polyurethane technology.
