New and Improved Formulation! We are excited to introduce our updated Medium Silicone Rubber. The new formulation maintains the same hardness but is now much more fluid, easier to mix, and sets faster – curing in just 4-6 hours, making your projects even more efficient!

Our Medium Silicone Rubber is perfect for most moulding and casting applications. It's soft yet firm enough to maintain its structure, which is ideal for a variety of casting projects. It also works well for moulding when a solid structure is required.
