Generally chlorofluorocarbons are derivatives of methane, ethane and higher alkanes containing Cl and/or F atoms substituted for H. They are (or were) used as refrigerants, fire extinguishers, cleaning solvents, in electronics for soldering. CFC's are used as building blocks (monomers) for many plastics. PVC and teflon are well-known examples. CFC's generally form molecular crystals low temperatures. The high temperature phase is usually orthorhombic. As orientational degrees of freedom are frozen out structural phase transitions to monoclinic phases occur. These crystal phases of CFC's are more effective at catalysing the destruction of ozone than the same CFC's in the gas phase.

well i think the previous answer pretty much covered the uses. if you mean different compounds that qualify as CFC's, there can technically be hundreds. any chlorinated and fluorinated hydrocarbon is a CFC.
