After mixing and coloring, silicone rubber can be extruded into tubes, strips, solid wires, or customized profiles according to the manufacturer's size specifications. Cords can be connected to form O-rings, and extruded profiles can be connected to form seals. Silicone rubber can be molded into customized shapes and designs. Manufacturers are committed to setting industry tolerances when extruding, cutting, or connecting silicone rubber profiles. In the UK, this is BS 3734. For extrusion, the closest level is E1, and the widest level is E3.

Silicone rubber is used in automotive applications, many cooking, baking and food storage products, including underwear, Sportswear and footwear clothing, electronic products, home maintenance and hardware, and many invisible applications.

Liquid silicone rubber is also used in life science applications (syringe piston, seals of distribution system, gaskets and respiratory masks for venous flow regulators, implantable chambers for intravenous injection), cosmetics (eye black brushes, cosmetics packaging, cosmetics applicators), lipstick molds and optical products (circular lens, collimator, Fresnel lens and free-form surface lens).

Frost resistant solar hot water panels utilize the elasticity of organic silicon to repeatedly adapt to water expansion during freezing, while maintaining a high temperature tolerance lower than the brittleness during freezing, and have excellent temperature tolerance above 150 ° C (302 ° F). It does not have a carbon skeleton, but its chemically strong silicon skeleton reduces its potential as a food source for dangerous aquatic bacteria such as Legionella.

Non dyed silicone rubber tape with iron oxide (III) additive (making it red orange) is widely used in aviation and aerospace wiring applications as splicing or wrapping tape due to its non combustible properties. Iron oxide additives can improve thermal conductivity, but do not alter the high electrical insulation performance of silicone rubber. This type of self fusing tape will self fuse or fuse, so when stretched and wrapped around cables, electrical connectors, hoses, and pipes, it will adhere to a strong seamless rubber like electrical insulation waterproof layer, although not an adhesive.

By adding carbon or another conductive substance as a powdered filler, silicone rubber can be made to have conductivity while retaining most of its other mechanical properties. Therefore, it is used as a flexible contact that closes when pressed, for many devices, such as computer keyboards and remote control earphones.
