About PTFE

PTFE is short for Polytetrafluoroethylene, a chemical applied to common bolting materials (such as B7 stud bolts) to provide corrosion and chemical resistance.

Normally when we talk about the  PTFE coated on the stud bolt and other fasteners,we always refer to  Teflon® and Xylan®.

PTFE coated studs have been used for many years within the bolting industry, especially in any application that requires corrosion resistance or in offshore applications.

While PTFE coated stud bolts (including Xylan coated studs  bolts) have corrosion-resistant properties.

PTFE coating ,also Teflon is a fluorocarbonsolid, as it is a highmolecular weightcompound consisting wholly ofcarbonandfluorine. PTFE ishydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigatedLondon dispersion forcesdue to the highelectronegativityof fluorine. PTFE has one of the lowest coefficients offrictionof any solid.

PTFE is used as anon-stick coatingfor hardware It is nonreactive, partly because of the strength ofcarbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals.
