Transforming Teflon into Toothpaste Ingredient
A reaction involving grinding PTFE with sodium metal creates sodium fluoride, a key ingredient in toothpaste, in a solvent-free process.
Polynetrafluoroethylene (PTFE), commonly known as Teflon, has evolved from a wonder material to a societal concern due to its unreactive nature and high heat resistance.
PTFE is used in nonstick cookware, industrial and medical coatings, electronic insulation, and as seals and gaskets when handling harsh chemicals.
Grinding PTFE with chunks of sodium metal creates sodium fluoride in a solvent-free reaction that aims to avoid landfills.
