ClearSil™ (Firm) transparent silicone rubber is a high quality platinum (addition-cure) silicone rubber ideal for creating moulds that require high clarity, firmness and stability.

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

Please take note that to create high clarity, bubble-free silicone moulds, ClearSil™  requires degassing (usually in a vacuum chamber). It may also be possible to remove bubbles with a pressure pot.

If the silicone rubber is not degassed, there will be many bubbles in the silicone mixture, although that generally does not affect the surface of the mould cavities.

It is non-toxic, food-grade, skin-safe and safe to use indoors. Cures at room temperature.

If you do not require such a high clarity silicone rubber, you may consider our translucent silicone rubber, IceSil (Firm) Silicone Rubber or IceSil (Soft) 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



The technical specifications and information is given in good faith and based on our test results obtained but without warranty. The information may differ when the silicone rubber is used in different environments, if pigments are added, or due to the material of the master or any external-related factors.
