In Situ IR Study of Thermoplastic Polyurethane (TPU) Reactions

The application of in situ IR spectroscopy has been widely used in industry for decades. The method can provide more insightful information on the reaction, which includes the reaction kinetics and possible intermediate(s) involved. Such information drives innovation in process modification and optimization. Lubrizol Advanced Materials is one of the leading manufacturers of thermoplastic polyurethane (TPU) globally. TPUs are engineered polymers that can be tailored chemically to be used in variety of applications. They bridge the gap between rubbers and plastic due to their unique performance, flexibility and melt processability.

In this webinar, applications of using in situ IR spectroscopy to monitor the TPU reaction were discussed, including:

  • Optimization of the mixing method in a polyurethane reaction
  • Determination of the reaction endpoint by examining the residual isocyanate level
  • Correction of non-linear response of isocyanate level in prepolymer reaction

The role of PAT differs drastically when it is used for development, scale-up or production purposes. With such changing roles, changes in the number of techniques and frequency of use are also observed. In this talk, these differences are described, and examples are shown for each of the roles. The talk then focusses on lab-to-plant scale-up. How can PAT be used to verify or deny a correct scale-up and, in the latter case, help in finding out why the scale-up was not successful. The fingerprint concept is explained, as well as recent advances on how to bring PAT data from the lab into the plant to allow for a Live verification and data analysis during batch scale-up.
