PTFE is a fluorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. It is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction of any solid.

Teflon (PTFE) orings are known for high resistance to chemical agents and solvents, anti-adhesiveness, high heat resistance, low coefficient of friction, and non-toxicity.
