Does styrofoam even have CFCs anymore? If not, that foam may well work.
You know, a quick google search yielded this...
"In Styrofoam and PS cups studies, hot water was found to be contaminated with styrene and other aromatic compounds. It was observed that temperature played a major role in the leaching of styrene monomer from Styrofoam cups..."
Apparently it's not so much the cfc's that will get you, but rather styrene itself. I usually try to avoid styrofoam for it's inability to ever really biodegrade being a petroleum based product, I had no idea it leached into water, coffee, etc so easily.
Perhaps some cork board affixed to the bottom of the dock would be a better alternative.
