Chlorodifluoromethane

Product Overview

Chlorodifluoromethane (CHClF₂), commonly known by its trade designations HFA-22, F-22, or FC-22, is a colorless, non-flammable fluorinated hydrocarbon gas with excellent thermodynamic properties. Historically utilized as a refrigerant and aerosol propellant, it serves as a critical intermediate in the synthesis of polytetrafluoroethylene (PTFE) and other fluoropolymers. While its use as a standalone refrigerant has been phased down under the Montreal Protocol due to ozone-depleting potential, it remains indispensable in controlled industrial synthesis and as a precursor in advanced fluorochemical manufacturing.

Specifications

Industrial Applications

Chlorodifluoromethane plays a pivotal role in the production of high-performance fluoropolymers such as PTFE (Teflon™), which are essential in aerospace, automotive, electronics, and chemical processing industries due to their thermal stability and chemical inertness. Additionally, it functions as:

• A key building block in the synthesis of hydrofluorocarbons (HFCs) and other environmentally optimized refrigerants.
• A blowing agent in the manufacture of rigid polyurethane foams for insulation.
• A process gas in semiconductor etching and cleaning applications under strictly regulated protocols.
