Abstract

Abstract A moldable article useful for making a form-stable article is described. The moldable article comprises a formable material that is a moldable polymeric or prepolymeric substance that can be cured to a form stable state and a curing agent, in close proximity to the curable substance but isolated therefrom, in frangible hollow fibers. In use, the frangible hollow fibers are ruptured to release the curing agent and the moldable article, in a first configuration, can be shaped to a second configuration in which it is maintained until the formable material is cured sufficiently for it to be form-stable in the second configuration. The moldable article can be used to make molds, casts, support for a portion of the human or animal anatomy, or other articles with diverse utilities.
