Market Characterizations

The AIM Act lists statutorily-established applications including: (1) Propellants in metered dose inhalers (MDIs); (2) defense sprays; (3) structural composite preformed polyurethane foam for marine use and trailer use; (4) the etching of semiconductor material or wafers and the cleaning of chemical vapor deposition (CVD) chambers within the semiconductor manufacturing sector; (5) on board aerospace fire suppression; and (6) mission-critical military end uses, such as armored vehicle engine and shipboard fire suppression systems and systems used in deployable and expeditionary applications. These reports describe EPA's current awareness of the use of HFCs and provide information on EPA's current knowledge on projected, current, and historical trends of HFCs related to these statutorily identified applications.
