PolyFoam Series Casting Foams
PolyFoam Series Casting Foams
PolyFoam Series Casting Foams consist of liquid Parts A and B that, after mixing, form self-skinning foams. PolyFoam can be used to cast rigid or flexible objects with densities in the range of 3-20 lb/ft³. Considered PolyFoam for production of decorative objects, lightweight mold shells, production parts, tools, models, patterns, fixtures, duplicate masters and general tooling use. PolyFoam systems do not contain toluene diisocyanate, MOCA, heavy metals or HCFCs, and are practically odorless. PolyFoam R-2, R-5 and R-8 are rigid foams. PolyFoam F-5 is flexible for casting soft parts.

PolyFoam R-5
PolyFoam R-5
PolyFoam R-5 is a 1:1 mix (by weight or volume) polyurethane self-skinning rigid foam that has a free-rise density of 5 lb per cubic foot. PolyFoam rigid foams are excellent for casting functional as well as decorative objects that need to be lightweight and rigid. Also great for lightweight mold shells or mother molds. Generally PolyFoam products are poured into TinSil or PlatSil silicone molds or PolyCoated Poly 74 & 75 Series polyurethane rubber molds.

PolyFoam R-8
PolyFoam R-8
PolyFoam R-8 is a castable rigid polyurethane foam demoldable in 10-15 minutes, this easy-to-use 1:1 mix rigid foam can be cast in closed molds packed to a density of 12 to 20 pounds per cubic foot to produce parts replicating wood, terra-cotta, stone or many other materials. It is usually cast in molds of PlatSil® 73-45 with Barrier PF and Pol-Ease PF.
