Rigid Foam (R-series PolyFoam)

R-8 Foam PolyFoam

PolyFoam R-8 is a two-part, rigid polyurethane casting foam. This self-skinning foam has a free-rise density of 8 lb/ft³, but should be cast at a density of 8 to 20 lb/ft³ to achieve good surface detail and mold fill. Generally, PolyFoam products should be cast in TinSil or PlatSil silicone molds. 

R-5 PolyFoam

PolyFoam R-5 is a two-part, rigid polyurethane casting foam. This self-skinning foam has a free-rise density of 5 lb/ft³, but should be cast at a density of 8 to 20 lb/ft³ to achieve good surface detail and mold fill.

These foams can also be poured into Poly 74 & 75-Series polyurethane rubber molds that have been coated with a PolyCoat Sealer and release agent.
