Foam cups are typically made from polystyrene, which does not contain chlorofluorocarbons (CFCs). However, some foam production processes in the past used CFCs as a blowing agent. Nowadays, many manufacturers have shifted to using more environmentally friendly alternatives, so most foam cups today do not contribute to CFC emissions.
What else can I help you with?
What are the sources of cfc's in the atmosphere?
the source of cfc is mainly from refrigerators n ac's...increase in the emission of cfc may lead to a hole in the ozone layer,the result of which is harmful rays such as ultra violet rays reaching out to people which causes skin cancer

How long does it take for water to boil in a foam cup?
It typically takes about 5-10 minutes for water to boil in a foam cup. However, caution should be exercised when boiling water in a foam cup as it can potentially melt or catch fire due to the heat. It is not recommended to boil water in a foam cup for safety reasons.
What cup will freeze water faster glass or a foam?
Water will freeze faster in a glass cup compared to a foam cup because glass is a better conductor of heat than foam. This means that the glass cup will transfer heat away from the water more quickly, leading to faster freezing. Foam cups insulate better and will retain heat, making the freezing process slower.
What is the main source of ozone-depleting chlorine in the stratosphere?
The main source is CFC's. They are present in deodorants.
