Measuring and Characterizing Tris(2-chloro-1-methylethyl) Phosphate Emission from Open Cell Spray Polyurethane Foam.
Understanding emission of Tris(2-chloro-1-methylethyl) Phosphate (TCPP) from spray polyurethane foam (SPF) insulation will contribute to the assessment of exposure to TCPP in indoor environments. This study aims to: (1) develop a method to determine the gas phase concentration of TCPP in equilibrium with the material phase (y0) for open cell SPF, (2) determine the partition coefficient for TCPP between air and SPF (K), and (3) examine the influence of temperature on y0 and K. The emission of TCPP from two kinds of open cell SPF in a closed micro-chamber without flow are being tested. The steady-state gas phase TCPP concentration in the chamber (Cequ) is also being measured. Cm0 (the initial concentration of TCPP in SPF) is measured using a solvent extraction method. Cequ and Cm0 will then be used to determine y0. These measurements are still in progress, and the preliminary results will be presented at the conference.
