![]() ![]() Logo of Teflon, the commonly known brand name of PTFE-based compositions manufactured by Chemours It is also frequently employed as a coating on catheters this interferes with the ability of bacteria and other infectious agents to adhere to catheters and cause hospital-acquired infections. It is commonly used as a graft material in surgical interventions. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery. It is non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. PTFE has one of the lowest coefficients of friction of any solid. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. Polytetrafluoroethylene is a fluorocarbon solid (at room temperature), as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine. The commonly known brand name of PTFE-based compositions is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. ![]()
