IceSil™ (Firm) translucent silicone rubber is a high quality platinum (addition-cure) silicone rubber ideal for creating moulds that require firmness and stability. The silicone rubber has a temperature resistance of 200 to 220°C, making it suitable for making baking moulds.

Moulds made with translucent silicone rubber are great for resin castings that require accurate colouring or if you require clarity when embedding objects in your casts.

It has great bubble release so you can create moulds without bubbles affecting the mould cavities. It is non-toxic, food-grade, skin-safe and safe to use indoors. Cures at room temperature. 

If you are looking for a translucent silicone rubber with greater flexibility, check out our IceSil (Soft) Silicone Rubber. If you require a transparent silicone rubber with higher clarity, we recommend using our ClearSil (Firm) Silicone Rubber

Note: The silicone rubber may not cure if there are contaminants on the surface of the master. As IceSil™ is a platinum (addition-cure) silicone rubber, contact with some materials such as sulphur-based clay, tin-cured silicone rubber, latex rubber, paint products and certain 3D-printed plastic, may also inhibit its curing process. Uncured rubber can be difficult to remove from your masters and may stain them. Hence, we recommend performing a small test on your master before making your actual mould.

Shelf Life

The silicone rubber has a shelf life of 1 year when stored under dry and cool conditions in sealed packaging.


Although the silicone rubber is non-toxic, it is still a chemical and you are advised to follow product usage instructions and wear personal protective equipment. For more information on safety, please refer to the SDS available at
