Until the beginning of World War II there was not any commercial production of fluorine. It was only the development of new nuclear reactors that brought up the need for producing fluorine. The technical progress allow nowadays the store and transport of fluorine quantities in an absolute secure way.
Fluorine is used in the preparation of organic compounds containing fluorine used in the production of hard plastics resistant to high temperatures (teflon), pharmacological products, toothpastes, cooling fluids and aerosol products (freon). It is also possible to use fluorine in rocket propulsion.
