- Abstract
- Chlorofluorcarbons were developed as refrigerants some 60 years ago. However, their application soon significantly diversified, owing totheir properties of non-flammability, chemical and thermal stability, and generally low toxicity. They are now used as blowing agents in foam insulation production, as propellants in aerosols, as cleaning agents of metals and electronic components, and to a lesser extent as chemical intermediates. Their current production is more than 1 000 000 tonnes per year with a market value estimated to be close to US $1.5 billion.
