ComposiMold-Firm is a firm mold making material that can you can simply remelt to reuse. It is also a 100% reusable mold making material that works by melting and pouring. Many casts can be made using the same mold. ComposiMold-Firm is an excellent material for those wanting to learn and become involved in sculpting, modeling, and mold making without having to worry about mistakes or wasting material. ComposiMold-Firm is a rubbery, thermoplastic that is great for small mold parts that require a stiffer mold making material. A stiffer mold is often required when using the push mold technique because pressure on a more flexible mold might deform the mold. ComposiMold-Firm is compatible with many different casting materials including clays, plaster, cement, epoxy, polyurethane, and many others.
It's Shore Hardness is approximately 25 at 70 F. Color is semi-transparent dark amber. Melting temperature is 130 F. The part solidifies when the temperature cools. To speed up cooling, place the mold in the refrigerator or freezer. PowerMold conforms to ASTM D4236, Safe as an art material.

This works great for my homemade polymer clay medals. Its stiff enough so that it doesn't deform but also flexible enough that I can easily pop the clay right out.

Power-mold works well for polymer clay push molds. You can make a variety of molds with the same material! It just remelts to make a new mold! It makes a very strong mold.
