Accurate Testing of Isocyanates for Safer Polymer Products
LCS Laboratory provides specialized testing to identify Total Isocyanates and residual Free Diisocyanates in both liquid and solid polymer samples. This service is essential for manufacturers aiming to confirm that their products are free of hazardous isocyanate compounds, ensuring compliance with safety standards and protecting end-users from potential health risks.
Why Is This Test Important?
Isocyanates are widely used in the production of polyurethane foams, coatings, adhesives, and sealants. However, residual isocyanates in finished products can pose significant health hazards, including respiratory and skin sensitization. Identifying and quantifying these compounds is critical to:
- Ensure Product Safety: Protect workers and consumers from exposure to harmful chemicals.
- Meet Regulatory Standards: Demonstrate compliance with industry-specific health and safety regulations.
- Enhance Market Credibility: Build trust by certifying that your products meet safety and quality standards.
Technical Details of Isocyanate Testing
Our testing procedure is based on a modified version of OSHA Method 47, specifically tailored for bulk polymer samples. The process involves:
- Extraction and Derivatization: Isocyanates are extracted from the polymer matrix using a derivatizing solution. This step stabilizes the isocyanates, preventing their degradation during analysis.
- Advanced Analytical Techniques: The stabilised extract is analysed using High-Performance Liquid Chromatography (HPLC UV), ensuring precise quantification of isocyanate compounds.
Isocyanates We Test For
LCS Laboratory can detect and quantify the following individual isocyanates:
- MDI (Methylene Diphenyl Diisocyanate)
- TDI (Toluene Diisocyanate)
- HDI (Hexamethylene Diisocyanate)
- IPDI (Isophorone Diisocyanate)
In addition, we offer testing for Total Isocyanates, covering a broader spectrum of compounds. Our detection limits are:
- Individual Isocyanates: 10 mg/kg
- Total Isocyanates: 50 mg/kg
