What are chlorofluorocarbons (CFCs) primarily used for?

Chlorofluorocarbons (CFCs) are primarily used in aerosol sprays and refrigeration due to their properties as non-toxic and non-flammable substances. They were widely utilized as propellants in spray cans and as refrigerants in air conditioning and refrigeration systems, making them essential in various industries. CFCs were favored because they effectively transferred heat and produced stable compounds. However, their usage has been significantly regulated due to their role in ozone depletion.

While there are other applications for the materials mentioned, the predominant historical and industrial significance of CFCs lies in their use in aerosol sprays and refrigeration technology. Understanding the specific applications helps contextualize the environmental concerns that arose from their widespread use, leading to the adoption of alternative substances.
