I found this in an old post by the lube engineer for MPC (formerly) and Steel Shield Tech (currently) and just thought I would add it:

Also, it is NOT the PTFE (chemical name: poly-tetra fluoro ethylene, or more commonly known as "Teflon" micro-powder) that bonds to the metal and reduces wear, as you say. PTFE has a hard enough time staying on frying pans and cookware, when the surfaces have been properly prepared by grit-blasting and manganese phosphate substrate prep-ing, prior to the application and baking.
PTFE will NOT bond to the surface, in a synthetic polymer-paste, but will act as a medium and thixotropy agent, buffering the contact areas of metal parts. PTFE is NOT the only halogenated substance present in the formula, as analysis and their load carrying capacity proves. PTFE cannot withstand extreme pressures over 150 psi, without rupturing and causing a deformation to the polymeric chain (kind of like squishing the wee balls of "plastic" into flat sludgy pieces). Aw, come on....what did you think PTFE was made of....Titanium alloy?....nope....its a fluorine polymer (plastic), whose formula looks like this:
CF2-CF2-CF2-(infinitely)
One carbon, attached to 2 fluorine atoms, over and over.
