Silicone is an inert polymer that is stable at a wide range of temperatures and resists water. It is used in medicine as prostheses (eg. breast), lubricants, sealants and adhesives. It is also used to coat the inside of some blood collecting tubes to prevent the blood from adhering to the tube. There is no scientific evidence that silicone is harmful to the body.
