A prosthetics grade silicone which is resistant to bacterial growth and is hypo-allergenic to prevent irritation. The material does not try out and is very soft and elastic.

It has a wide range of uses from medical prosthetics and cushioning applications to creating skin effects, other movie special effects and animatronics. It can also be used as very soft and stretchy moulding material for casting resins, plasters, waxes and soaps etc.

The two odourless and non-toxic components mix easily with a simple mixing ratio of 1:1 and because of the very low viscosity can be used without processing in a vacuum chamber.

The cured rubber is a translucent beige/off white colour that is a very flexible, elastic material with high tensional and tear strength. There is almost no shrinkage (0.1%) and excellent reproduction of fine detail. It has a long mould life with outstanding release properties. Being an addition/platinum cure rubber it has excellent dimensional stability and will resist deforming providing a long library life.

The colour of the cured rubber can be changed with the addition of a colour pigment during the mixing of the two components. We have a range of compatible colour pigments click here


When using this material to cast into a silicone mould a release agent is required click here


It can be softened to your own requirements using this softening additive click here


Can be made thixotropic for applying to vertical surfaces or to over head objects click here

A release agent will not create a sufficient barrier to prevent cure inhibition but a layer of paint will. If the paint is solvent based allow sufficient time for the solvent to completely evaporate off as that too can inhibit the cure

Great care must be taken when handling and mixing all addition-cured silicone elastomer systems. All the mixing tools (vessels and spatulas) should be clean and constructed in materials which do not interfere with the curing mechanism. The cure of the rubber can be inhibited by the presence of compounds of nitrogen, sulphur, phosphorus and arsenic; organotin catalysts and PVC stabilisers; epoxy resin catalysts and even contact with materials containing these substances e.g. moulding clays, sulphur vulcanised rubbers, condensation cure silicone rubbers, some printed plastics, onion and garlic.
