We stock silicone rubber for making molds and re-usable vacuum bags.
Silicone rubber is great for molding parts that have complex geometries like skulls, hands, climbing holds, shifter knobs, and other complex parts. It holds detail well and then can be flexed off of the part.
Silicone rubber also has a high coefficent of thermal expansion which allows it to be used as mandrels in heat cured composites to add pressure to the cure cycle.
Tin Cure silicone rubbers are easy to use and compatible with a wide variety of materials.
Use for molds, mandrels, or even parts like gaskets and seals. Easy to use tin cure formula cures against a broad variety of substrates INCLUDING sulfur clay.
Holds fine detail and is pourable. It can be made brushable with the addition of a thickener.
Stretches up to 400% which is great for use as mandrels in hollow parts, also great for casting where you have 3 dimensional parts with fine detail and under cuts.
Great resistance to chemical attack, works well with polyurethanes and epoxies. Some materials that are commonly cast into this are: Urethane, plaster, soap, wax, polyester casting resin, and epoxy.
