Generally, Polytetrafluoroethylene (PTFE) is used to coat cooking pans giving them wonderful non-stick properties.
PTFE is composed of carbon and fluorine atoms, which form very strong chemical bonds with each other.
Fluorine atoms also have the highest electronegativity of any element, meaning the overall electrical forces,
known as van der Waals forces, cause compounds containing fluorine to repel any other atoms that come near,
making this a perfect water and dirt repellant, keeping the chain clean and running smooth.
