This foam polyurethane formulation is designed yield structural foam by either hand-mixing or machine casting method. Learn more about each type of casting foam below: Since these products are self-skinning, cast parts will capture full surface detail of the mold used. The higher a foam"s number (or pounds per cubic foot), the denser the foam. Most of our foams are "closed cell," or self-skinning formulas. Generally, PolyFoam products should be cast in TinSil® or PlatSil® silicone molds. Casting Flexible Polyurethane Foam: I have been making a series of 3D printed molds recently (see Making a 3D Printed Mold) and figured I should explain how I'm doing the casting. FOAM-iT! Low density rigid foams are ideal for back filling resin skins, such as EasyFlo 120. Rigid Casting Foam c PolyFoams are practically odorless and do not contain toluene diisocyanate, MOCA, heavy metals or HCFCs. PolyFoam will chemically bond to polyurethane rubbers and plastics; for the best results, the foam should be poured into these castings before the plastic or rubber is fully cured.

Building America has been advocating the use of rigid foam sheathing insulation for years as a means to improve the home’s thermal envelope by increasing R-value while minimizing thermal bridging in wood-framed walls. Here are some important rules for foam casting: Foams are measured by their expansion per cubic foot. Rigid Urethane Expanding Foams FOAM-iT!™ 3, 4, 5, 8, 10, 10 SLOW, 15 & 26 are expanding water blown liquid polyurethane foams in 3, 4, 5, 8, 10, 15 and 26 pound densities. Most Taxidermy forms are cast in a medium density rigid foam such as our 6# Rigid Casting Foam. If restricted, or cast in a closed mold, the expansion will be lower. A 2# foam for example, is 2 pounds per cubic foot once expanded and cured. They are manufactured using our unique chemical formulas to be exceptionally uniform and consistent in all physical properties. SiliFoam will chemically bond to silicone rubbers, but should be poured against the silicone before the silicone has fully cured.
