Tooling foam wanted.
(OP)
We're after a foam for use under vacuum and 150 deg C to maybe 180 deg C.
We think something roughly akin to Rohacell 31 PMI would do it, but Rohacell is a bit out of our budget and a bit frangible. We're more after a tooling material rather than a production one. We'd quite like to move even father away from production type materials and use a two-part foam.
Does anybody out there use a product of this type that you'd recommend? The temperature is the problem.

Also maybe try Aquacore(machinable) or Aquapour (castable) ht
Obviously the aqua line is geared more for being a dissolvable mandrel, but I have had much luck in using it for quick tool prototyping..

It seems that while the common polyurethane foams are all low temperature, you can get polyisocyanurates which are good for the temps we're after.
