ComposiMold-Firm is a firm mold making material that is also a 100% reusable mold making material. It works by melting and pouring. ComposiMold-Firm is a flexible, rubbery, thermoplastic that is great for mold parts that require a stiffer mold making material. It is compatible with many different casting materials including clays, plaster, cement, epoxy, polyurethane, and many others. You can use ComposiMold-Firm for polymer clay push molds such as Sculpey molds or Fimo molds. It also works well with polymer metal clay molds.

  • REMELTABLE
  • REUSABLE Over 35 Times!
  • Certified FOOD-CONTACT SAFE MOLD MAKING MATERIAL


ComposiMold-Firm is designed predominantly for Polymer Clay Molds. Plus many cake decorators enjoy the more firm version for modeling chocolates and firmer fondants.

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. Do not place the mold in water.

ComposiMold-Firm conforms to ASTM D4236, Safe as an art material. 

Although, the reusability means you do not need to dispose of the ComposiMold, it is compostable. ComposiMold is a unique, innovative product designed to enhance you mold making experience. It is a reusable mold making material that can make many molds and castings with only one mold making material. ComposiMold provides a unique solution to sculptors and artists by allowing molds to be easily fixed by either using heat to reshape the mold or by re-melting the composite and starting the mold over. The current record for the number of unique molds made with the same ComposiMold is 55. For this test, the ComposiMold is melted, a mold made, a part cast, and the cycle repeated. ComposiMold’s formulation provides a stable system with good mold strength, elongation of 150%, and longevity. ComposiMold is the easiest, most flexible molding system available: melt, pour, and use. It is also important to note that no dangerous chemicals are used in the product and therefore safe for both the end-user and the environment. ComposiMold’s key advantage over other mold making materials is the fact that the product is reusable. Compared to other mold making products, ComposiMold has lower costs due to the change in the paradigm. Since the mold can be reused multiple times, the more you use the product, the more money you save. Be sure to use the proper mold release for your project. ComposiMold – LT Amber color, medium stiffness, Shore A: 10-15, Elasticity 150% (describes the amount of stretch before breaking. 150% elongation means a 1 inch piece can stretch 2.5 inches before breaking), Good stiffness for many molds, Easy to handle part undercuts, easy to mold while still providing good strength.
