Polytetrafluoroethylene

Polytetrafluoroethylene is a really, really long name for a special type of material that people use to do all sorts of things, like cooking, car parts, and even making clothes. It's made up of tiny parts called molecules, and these molecules are really strong and don't like to stick to other things. Because of this, things made with polytetrafluoroethylene are very slippery, and nothing can stick to or stain them. It's almost like a superhero material that can't be defeated! And even though it's a big, complicated name, you can just call it PTFE if that's easier for you to remember.
