Is it a vacuum cup with fluorine coating that affects the health?
The elemental substance of fluorine is F2, which is a pale yellow [1], highly poisonous gas. Fluorine gas corrosion is very strong, very active chemical properties, is one of the most oxidizing substances, and even some inert gases can react under certain conditions [2]. Fluoride is a special plastic, rubber and freezers (freon-12) key elements in. Because of the special chemical properties of fluorine, fluorine chemistry plays an important role in the development of chemistry.
Fluorine is a nonmetallic chemical element, chemical symbol F, atomic number 9. Fluorine is the halogen elements of a periodic system of A VII family, located in the second period in the periodic table of elements.
Does not affect the health, only in the temperature of more than 200 degrees will be long life of harmful substances.
