Silicone rubbers come in various types. The best known is the one-component silicone rubber. There are also rubbers made from two components. So you will always find the perfect rubber for your project.
If you intend to cast tin or lead, for example, you should use silicone rubbers that can withstand high temperatures for a short time. The single component silicone rubbers are usually used as a joint sealant or to seal seams and joints.
The range of rubbers consisting mainly of two components includes several variants of polycondensation curing rubbers. For example, there are silicone rubbers suitable for applications in the food industry, such as processing or moulding chocolate and marzipan.
In addition, it is possible to thicken the casting rubbers to make them spatterable. This is particularly useful for making peeling moulds.
