RTV Silicones

RTV silicone rubber, a 2-part liquid, is used for casting moulds that are flexible, durable, and offer excellent release for materials such as resins and low-melt metals, making it ideal for creating props, models, art, decorative objects, jewellery, prototypes and more. 

Mouldlife | PS offer a range of RTV silicones from Platinum Cured (also known as addition cured) to Condensation Cured (tin based) with a Shore Hardness from as low as a 0030 to much harder silicones of over 60A.

As the UK's official distributors of Polytek, we hold the largest range of market leading prosthetic silicones like Platsil Gel 00 and Platsil 10 in the UK. We are also very proud to offer the Elkem and Dow Corning range of silicone.

We supply silicone rubber for a wide range of mould making projects to suit every level of expertise. To help you choose the correct RTV silicone and get the most out of your purchase, we recommend you call our office (01638 750 679) and speak to one of the technical team. You can also learn more about the major differences between RTV addition cured (platinum cured) silicones and RTV condensation (tin based) silicones, or you can read our article on the best mould making silicone.
