First Reactive Extrusion Simulation.
What appears to be the first software to simulate twin-screw reactive extrusion is under development at PolyTech, an engineering consulting service in New Haven, Conn. PolyTech's existing "TXS" twin-screw simulation package will be modified to include known reaction simulations used in modeling large polyolefin reactor processes. The adaptation was requested by resin producers, who impart special properties to resins in post-reactor processing and wanted better understanding of reactive compounding. PolyTech is inviting additional sponsors (such as polyolefin compounders) to join the project, and expects to finalize the roster of participants by September. Interested firms should call PolyTech's sales representative at (570) 992-0961.
