Data for Component: Paraffin waxes and Hydrocarbon waxes, chlorinated 
Movement & Partitioning 
Expected to be relatively immobile in soil (Koc > 5000). Given its very low Henry's constant, 
volatilization from natural bodies of water or moist soil is not expected to be an important fate 
process. 
Henry's Law Constant (H): < 1.0E-07 atm*m3/mole; 25 °C Estimated 
Partition coefficient, n-octanol/water (log Pow): > 6 Estimated 
Persistence and Degradability 
Expected to degrade only slowly in the environment. 
Data for Component: Isobutane 
Movement & Partitioning 
Bioconcentration potential is low (BCF less than 100 or log Pow less than 3). Potential for 
mobility in soil is very high (Koc between 0 and 50).  
Henry's Law Constant (H): 1.19E+00 atm*m3/mole; 25 °C Measured 
Partition coefficient, n-octanol/water (log Pow): 2.76 Measured 
Partition coefficient, soil organic carbon/water (Koc): 35 Estimated

Data for Component: Isocyanic acid, polymethylenepolyphenylene ester, polymer with 
.alpha.,.alpha.',.alpha.''-1,2,3-propanetriyltris[.omega.-hydroxypoly 
Movement & Partitioning 
In the aquatic and terrestrial environment, movement is expected to be limited by its reaction 
with water forming predominantly insoluble polyureas. 
Persistence and Degradability 
In the aquatic and terrestrial environment, material reacts with water forming predominantly 
insoluble polyureas which appear to be stable. In the atmospheric environment, material is 
expected to have a short tropospheric half-life, based on calculations and by analogy with 
related diisocyanates.
