How to Minimize Hazardous Residual Isocyanate in Polyurethane Polymerizations

Isocyanate in Polyurethane Polymerizations

Isocyanates are the most critical building blocks for the performance polyurethane-based polymers that make up coatings, foams, adhesives, elastomers, and insulation.  As manufacturing volume has risen, concerns have increased over both product quality and the toxic health impact of a residual isocyanate.   In situ monitoring with process analytical technology provides process understanding to quantify isocyanate (NCO), polyol, by-products, and pre-polymer concentrations in real-time.

This paper describes experimental results where in situ mid-infrared spectroscopy was applied to ensure that the following are met:

  • Product Quality Specifications
  • Personnel Safety
  • Environmental Regulations

This enables a safer work environment and ensures residual NCO concentration meet standards, while optimizing production capacity and lower operating costs.
