Foamex is, I believe a skinned, foamed pvc sheet.  I have used it a lot for sheet parts, having been given a load by a sign-printer


it glues (reluctantly) with any of the solvent styrene glues, but would glue perfectly with plumbers pvc glues (I didn't try that, I would have had to buy it)


And it takes paint well.


AAArgh - I have just Google Foamex and found in Aus its a company who work in Polystrene!   >:-o


so Yes, we need to be careful with names and descriptions

So what's the type of foam used in foamboard and foamex? Did anyone ever tried to remove the paper from the foam board to use only the foam?

I went looking as well and found the same site, but a bit further down in the Google list there was
http://www.plastix.com.au/materials_foamed_pvc.html

It doesn't mention being skinned though

The foam used in foamboard sheet is polysyrene foam, and indeed the paper (card) front and back can be removed by soaking to leave a sheet of ps foam WHICH IS NOT SKINNED (Depron foam is skinned), so it is very flexible


OK so there are two meanings of Foamex
A) a brand name for Skinned PVC foam much used in the sign-printing industry, point of sale etc (hence the skins so it can be printed on)
and
 B)   In Australia (?only) the name of a company selling insulation products and the brand they put on their polystyrene insulation products (both extruded and expanded)


So, as usual, be careful out there, folks :-)
