Mini Puzzle Silicone Mold (4 pieces each is 2.3*2*0.5 cm)

Silicone molds can be used to cast a variety of materials, including polyurethane, polyester and epoxy resins, polyurethane foam, plaster, wax, concrete, low melting metals, and more.

One of the primary advantages of using silicone mold rubbers instead of other flexible materials, is that release agent is not needed when casting polyurethane resins, foams and other materials into silicone molds. This is especially important when cast parts need to be painted as paint will not adhere well to parts with residual release agent.
