All,
   While talking to some of the guys in the machine shop here at the 
engineering building, I happened to notice that they were using 
expanding urethane foam for insulation on a river-bed sampler.

The urethane foam was from a company called US composites.

Urethane Pour Foam
15x volume expansion
mix 1 / 1 - Part A / Part B
45 second pour time

For all products:
http://www.uscomposites.com

Just the foam:

Prices were $18.50 for a 4Lb kit - covers 2 cubic feet
16Lb kit $54.00 - covers 8 cubic feet
These prices are for 2lb density foam (foam weighs 2Lbs / cubic 
foot), but they also sell 3, 4, 8, and 16lb..

I hope this helps..
