Causes for the Ozone Hole

Chlorofluorocarbons or CFCs which are used in refrigerants and coolants. CFCs are typically heavier than air, but they can ascend in the atmosphere in a process that takes 2-5 years. 
Once in the stratosphere, UV radiation break apart the CFC molecules into dangerous chlorine compounds which are known Ozone Depleting Substances (ODS). 
The chlorine literally slams into the ozone and breaks it apart. In the atmosphere a single chlorine atom can break apart ozone molecules again and again and again.
