Addition Cure Silicone

Also known as platinum-cure silicone, addition cure silicones exhibit the lowest long-term shrinkage and have the longest library life of all mould rubbers.

While good for making moulds for casting a variety of materials, addition cure silicones also have physical properties that other rubbers do not. As a result, they are used for other applications. For example, some are certified “skin safe” and can be applied directly to human skin.

They are also used for making prosthetic and orthotic devices, skin safe appliances and effects, etc. Some are certified “food safe” for culinary applications.
