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.
