Description of key information
Additional information
HFC-143a is only released to the atmosphere during manufacture and use. Due to its high Henry's law constant of 11.2 kPa m3/mol and low adsorption potential, it will partition mainly to the atmosphere following emission to the environment.
Fugacity-based model (U. S. EPA 2008) predict that upon release to the air, over 99.9% will remain in the air and less than 0.1% will partition into the combined soil and water compartments.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
