Tooling foam wanted.

Tooling foam wanted.

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.

RE: Tooling foam wanted.

I have used a few different products from General Plastics in the past with good results..They have a product which should hold up to about 195C...

Also maybe try Aquacore(machinable) or Aquapour (castable) http://www.acrtucson.com/products/Aquacore/index.htm

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..

Thanks samplesecond. The General Plastics website had a candidate material, plus it pointed us to Tepan, who also had a two-part candidate.

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.
