Silicone Rubber

Dragon Skin is a milky, moist to-the-touch, membrane-like silicone that is often used in prosthetics, animatronics and orthopaedic and cushioning applications. This material is so stretchy that a mould of it can be turned inside out without risk of tearing it. The material is supplied in two parts, one of which contains a platinum catalyst which causes the liquid polymer to cure into a solid object. Because silicone rubber flows easily and can be moulded, pressed or extruded using relatively low amounts of energy, it is a useful material for tinkering and making prototypes without specialist equipment. It is generally non-reactive, stable, and resistant to extreme environments and temperatures (from about −55 °C to +300 °C) so can be used for a huge variety of things, from making muffin trays to medical implants.
