Platinum cure molding rubber silicone rtv is used for prototyping and the reproduction of parts. Silicone moulds can be constructed in many different forms depending on the shape of the part you are making. In this section we will outline how to create the easiest one part flat back mould.
Features of platinum cure molding rubber silicone rtv
1. Good characteristics of easy-operation
2. Light viscosity and good flowability
3. Low shrinkage
4. Favorable tension
5. No deformation
6. Favorable hardness
7. High temperature resistance, acid and alkali-resistance and ageing resistance
8. Food grade, non-toxic
