Why are fluorocarbons (FCs) widely used?

Fluorocarbons (FCs) are widely used primarily due to their chemical stability. This characteristic allows them to remain intact and not degrade easily under a variety of conditions, which is particularly beneficial in refrigeration, air conditioning, and aerosol propellant applications. Their stability means that FCs do not react readily with other substances, leading to an extended useful life in products and processes where consistent performance is essential.

The stability of fluorocarbons contributes to their effectiveness in applications requiring a reliable refrigerant or solvent, where other compounds may break down or react negatively under operational conditions. This quality makes them appealing in industries where durable performance is critical.

While cost considerations can influence the selection of a refrigerant or solvent, chemical stability is often a more decisive factor in choosing fluorocarbons over other alternatives. High toxicity would not be an advantage in their use, as substances that are toxic can pose health risks to humans and the environment. Similarly, although FCs can have a significant atmospheric lifetime, it is their chemical stability that directly affects their functionality and usage in various applications.
