Moldmaking with Silicones – an Introduction
What advantages does silicone rubber offer for moldmaking and prototyping? What are typical applications? And why are confectioners, restorers and industrial users alike all sold on silicones? You will find an overview here with links to additional information.
Silicone Elastomers: A Multifaceted Material
The unique property profile of silicone rubber compounds makes them indispensable in a variety of industrial applications. In moldmaking and prototyping, the most convincing properties are:
Colored or Transparent Materials Available
When used for rapid prototyping, transparent grades allow manufacturers to cut the master from the silicone mold. With colored compounds, you can check the correct application of the silicone compound for skin molds.
Resistance to Many Reproduction Materials
Silicone rubber can be used for virtually any reproduction material, from plaster and wax to concrete and even low-melting metals. Special grades of silicone rubber are recommended for certain casting resins.
Highly Accurate Molds
Silicone elastomers yield molds offering an exceptional level of detail and precision. Also, molds made from addition-curing curing grades reproduce dimensions with complete accuracy.
Easy to Mix
Silicone moldmaking compounds consist of two components that can be blended at room temperature using either a spatula or stirring equipment. Products with a 1:1 mixing ratio are available for particularly easy dosing.
Compatible with Food
Some of our products are suitable for food contact and meet the requirements of corresponding FDA standards.
High Heat Resistance
Silicone elastomers retain their properties even in prolonged heat (+180 °C). Specialty silicone rubber grades are even suitable for casting low-melting metal alloys (maximum melting point: 270 – 300 °C).
Easy to Demold
Silicone rubber yields flexible molds that can be used without release agents. Even complex geometries release quickly and easily as a result.
Excellent Low-Temperature Flexibility
Molds made from silicone rubber remain flexible even at prolonged low temperatures (down to -50 °C).
