I believe this is the foam used in NASCAR to improve crash safety.
Have no idea what treating a six-gallon tank would cost.
This was one of my "Top Ten Ercoupe Improvements" suggestions
on FLYIN way back on February 5, 2003:
2. An "approved" four-gallon nose tank shortened from the rear
for better instrument clearance with NASCAR fire foam
inside.

Great idea (since I was thinking the same thing....but thought it was
only for military so far).
EAA should have records of the vendors at Oshkosh if you can remember
the year(s).

The last times I was able to slowly go through the vendor’s buildings
at Oshkosh, many years ago, there was always a display of a metal
sandwich of crumpled metal. The tank would be opened and filled with
this stuff then re-sealed.
The stuff allowed free, but slow, flow of fuel in the tank while only
using up 3% of the volume. The tank could not gush out its fuel.
They showed video of tracer rounds being shot through the tank and,
while the fuel would flow out and catch fire, it came out slowly
enough that there was a small flame – no gush, no fireball.
Is this stuff still on the market? If so, does the FAA approve this
for certificated planes or is it only for experimentals? Is this an
option that might work instead of the bladder idea?
