Transforming Teflon into Toothpaste Ingredient
A reaction involving grinding PTFE with sodium metal creates sodium fluoride in a solvent-free process, aiming to reduce landfill waste.
Polytetrafluoroethylene (PTFE), commonly known as Teflon, has evolved from a wonder material to a societal concern due to its unreactive nature and high temperature resistance.
Initially, PTFE was used in nonstick cookware, industrial and medical coatings, electronic insulation, and as seals and gaskets for harsh chemicals, including preventing uranium hexafluoride leaks during the Manhattan Project.
Grinding PTFE with chunks of sodium metal creates sodium fluoride in a solvent-free reaction that aims to avoid landfills.
Author's summary: Teflon is transformed into toothpaste ingredient through a solvent-free reaction.
