Silicone Mold Making and Tooling

Rudolph Bros. & Co. mold making compounds are two-component, room temperature-vulcanizing silicone (RTV) rubbers with excellent fidelity of reproduction. We offer suitable grades, condensation and addition cure, for making all kinds of molds, no matter how intricate, and for use with all types of reproduction material, whether wax, plaster, polyester and epoxy resins, urethane foam, or low-melting metal alloy. Thanks to their great flexibility and outstanding release properties, our mold making rubbers separate easily from the model. Their high resin resistance means they can be used over and over again. All of these excellent processing properties make our compounds indispensable for mold making; whether for industrial manufacturers or for artists and craftsmen.
