Specialist RTV Silicone Rubber

Specialist RTV Silicone Rubbers for Home Hobby and Industry. Here you will find a mix of more specialised liquid rubber systems that have over and above the usual properties of our standard range RTV Silicone Rubbers.

We have Heat Resistant RTV Silicone Rubber, which has a maximum service temperature of 300 Celsius (with spikes to 350 short term so ideal for pouring lead), Food Safe Certified RTV Silicone Rubber for chocolate, sugar and food moulds, Translucent RTV Silicone Rubber for clear moulds and difficult patterns which is also pigmentable using Silicone Oil Dispersions or indeed Artists Oils and in three hardnesses as well.

We also offer a pre coloured black RTV silicone with the same hardness options as the clears, which are all now 1:1 addition cure silicone rubbers and appear in that section also.
