ptfe additive

PTFE (poly tetra flouro ethylene) has fantastic lubricity properties. Examples of this is seen in Pressing Iron (used to press clothes), cooking utensils etc. In all cases the components are "precoated", I REPEAT "PRECOATED" and not applied to equipment while in use.

If anyone tells you that they charge PTFE into the lube sump along with the lubricant and the PTFE coats itself on the piston rod and cylinder dont believe it, it is just not possible. This logic applies to the Tubines and Paper machinary indicated in your query.

However if engine manufacturers pre coat the PTFE film on the piston rod and cylinder, may be it would be different ball game altogether. But no-one seems to have done it and talked about it.

So let us leave PTFE for precoated components and not add it to engines, turbines or other machinary.

My boss has decided to make this treatment both in the turbine lubrication system and paper machines. I am very worried about the consequences we could face in the future.Please any suggestion will be appreciated I need to change his angle.

THis is going to stir up some deep $$#&
The good thing here is if you don't like your boss let him go...the PTFE will plug up the filters. NOTE the origional manufacturer of Teflon is also a maker of liquid lubricants (oils) they don't use PTFE with their products, intended for circulation in circulating type systems, that in and of itself should speak volumes to you.
Sometimes you need to protect your BOSS from himself......

Completlly agree with both comments, in addition to all the problems already described, regarding the size of the ptfe particles you will find alterations in bearing vibration analysis.
PTFE have very good performance in some applications, yours are not in the list.

I read with interest the coms. I've just received documentation on a product named Centron II. After a metal pre-treatment flush, the treatment talks of a polariser that places a cationic charge on enginer / gear parts, this being a chemical lock for further treatment. Following this is the anionic treatment which consists of an M.C.F. fraction (?) and a P.T.F.E. fraction. The documentation claims 10+% reductions in power, heat generation. 3 fold reductions in wear and smoother wear profiles and reduced vibration. The documentation also comes with significant references and test results by university bodies. The vendor is local to Australia and web searches reveals little on the product. I am a sceptic too and think that if it is so good, I should have heard of it. Your comments ?

Dipen,

Sorry no website - which is one thing that make me dubious. If it was that good the world would be abuzz.

Alan,

I hear you, but before I run completely I'd like to check the following:
- One of the states in Australia has an electricity supplier that supplies 2/3 of the state and supposedly uses the stuff with their generators;
- also I'd like to chase up the university that conducted the tests on Centron II.

Will keep you posted.

Suggest that you do not put any additive with solids (teflon) that will either drop out in to the sump or oil pan or will be filtered out by the system. Check out Dupont and see what they say about PTFE in this application. Other solids have a buildup problem over a small percentage. Zinc and Moly for eg: more is not better.

Check out www.lubecorp.com ie Powertrain

ptfe is always, without disclaimer, a bad idea. The same goes for every halogenated anti-wear additive I've see.

Generally addition of any additive to used lubricant is discouraged.

The same goes for PTFE,definitely not in a turbine Ohooof .......
