Finally a safe way to use PTFE??

They have avoided the tribological implications and concentrated only on the chemistry.
What happens when shearing forces are applied to the surfaces and this soft PTFE gets sheared-off?
The rate at which the coating can be reapplied is very important, and if it takes a long time for the PTFE to rebond, then it does no good whatsover.
Gear lubricants faced this same problem when lead additves were first added to gear oil. The lead was sheared faster than it could replenished when the newer, higher rpm gearing came onto the scene, which resulted in high wear.
Most applications for PTFE only see an advantage when the PTFE is in solid form and bonded or impreganted into bearings that serve journals that turn very slow. PTFE is NOT a high RPM
lubricant.
And lastly, what happens when the flourine becomes dissasociated from the rest of the molecule during high temperature decomposition?

Oh, PLEASE...more techno-babble...
I mean the Techrobond, not MolaKule's reply!!
I know the esteemed members of this board already know this, but for the benefit of any noobs:
"Teflon is not useful as an ingredient in oil additives or oils used for internal combustion engines."
(This is from DuPont, the world's biggest supplier of PTFE...any questions?)

Not that this means anything as Molekule pointed out the site missed some important questions on the questionable use of PTFE in gasoline engines.
Just to remark, if University of Texas at Arlington is quite respectable...in whatver research the were hired to complete. It may not be as massive and well known as UT in Austin
or Texas A&M or Rice Univ in Houston but from 1st hand experiance they have 1st rate grad and fellows working the labs.
Credible research source, questionable marketing.
