Urethane FoamThis guideline explains how to handle cold pour polyurethane foams and mold preparations.
SFoam80 Flexible Polyfoam
5.0lb density flexible foam with an integral skin. Common uses include impact absorbing bumpers, special effects props and arm rests. Medium-firm consistency, expands approx 5-6 times volume, depending on casting conditions.
Size: 1.8kg, 7.2kg
SFoam130 Flexible Polyfoam
8.0lb density foam with an integral skin. A slightly firmer product than SFoam80, with a tougher skin. Great for those tough but lightweight props. Also good applied as a skin into a mold and backed with SFoam60. White in colour. Expands 2-3 times its volume, depending on casting conditions.
Data Sheet - MSDS Part A - MSDS Part B
Can be pigmented with BJB urethane pigments to give a solid colour result.
We have also tried some of the PSTF translucent dyes, for interesting pastel colour effects.
SFoam60 Flexible Polyfoam
60 Kg/m3 - This soft foam is ideal for puppets, backing up latex & soft flexible urethanes, and most SpecialFX applications. Expands 6-8 times its volume, depending on casting conditions. Cream in colour. Can be pigmented.
Size: 1.45kg, 2.9kg, 7.25kg
Note: In the photos, we cast a Soft Foam 60 face, which was rough and slightly cellular on the surface. We then did another cast where we brushed Flexicast BR into the mold first, then backed up with Soft Foam 60. This gave a much smoother, and stronger skin.

SFoam48 Soft Flexible Polyfoam
S-FOAM 48 is a 48kg/m3 density foam specifically developed for low-density molding. Higher densities may be achieved in closed or restricted molds. S-FOAM 48 is great for backing up latex skins, polyurethane elastomer skins and all kinds of SpecialFX and puppetry.
Size: 1.5kg, , 6kg
RFoam100 Rigid Polyfoam
R-FOAM 100 is a NON-CFC molding system designed to allow the manufacture of self skinned or structural components. The system exhibits excellent flow characteristics and can be either hand or machine mixed. Apart from the hard skin, the final moldings have a high softening temperature combined with high compressive and flexural strengths. This system will perform best with both components adjusted to 25˚C and molds at 25-40˚C.
RFoam 100 can be used as an in-situ cavity filling material. Suits construction panels and is widely used in taxidermy applications. Can be used as backup material to solid-fill a casting, where lower weight overall is required. Can be carved and sculpted once set. Cream in colour. Can be pigmented. Expands 8-10 times its volume, depending on casting conditions.
Size: 1kg, 2.kg
