Abstract
A molding compound for molding body portions preferably serves the purpose of producing a counterpart for the production of a model for making prostheses, particularly teeth prostheses or orthopaedic prostheses, or the purpose of cladding such prostheses for adapting same to a changed shape of body portions. This molding compound consists of a silicone containing pressure-elastic hollow microspheres the thin shell of which consists of a vinylidene chloride copolymer and the interior of which contains a gas. This silicone is initially liquid or pasty and, respectively, kneadable and solidifies after a certain time to a rubber-like consistency by adding a hardener, so that the molding compound reproduces the shape of the body portion to be molded.
