Which FREON fluorocarbon could improve your process? A WIDE RANGE OF BOILING POINTS, but other properties remarkably similar from one to the other—that's the interesting feature of the FREON family! Here's the unique combination of properties which apply to all FREON compounds regardless of boiling point: 1. High thermal stability 6. Very low toxicity 2. High chemical stability 7. Outstanding dielectric properties 3. Selective solvency 8. Low surface tension 4. Immiscibility with water 9. Low viscosity 5. Nonflammability 10. High density So whatever the operating temperature of your process, there's a FREON compound which you should evaluate. Have you an idea where any of this unique family of chemicals could be used? We'll help you develop it if you do! Clue: FREON products are used today as refrigerants, aerosol propellents, foam blowing agents, solvents, fire extinguishing agents, di­electrics, heat-transfer media, polymer intermediates and aerospace prod­ucts.
