914World.com _ 914World Garage _ Help me figure out what make with this.

What is it ?
Polytetrafluoroethylene
Size - I have a bunch cut at 1.75"x1.75"x2" and some strips at 1.75x1.75 at 36"
So I can mill or lathe these to make parts easily.
The material is known as PTFE
Otherwise know as Teflon
The question is what to make with it.
My 1st thought was a late shifter bushing at the trans. Some have been made out of Brass, but this would be the best possible material.
Then Pedal bushings were another thought, but instead of making a product that once the supply dries up I won't be able to make as the cost would be prohibitive, it needs to be a part that clearly this is the best material.
So I put this out to the brain trust - What to make ?
Here's some more properties
Melting point is about 327 C
It's chemically inert
It has a VERY low coefficient of of friction - nothing will stick to it.
It is flexible under a wide temperature range even very cold
What to make?

I've never had good luck with PTFE bushings. They always seem to cold flow and thin.

Rear lid torsion spring rollers?

Rollers would be easy, we already make them in Delrin. I don't think the upgraded material would yield any better attributes for the part.

Watch the movie “dark waters”
Read the most recent ban that the FDA has put out.
Be cautious regarding how you use it, machine it …all of tgat.
Be concerned with how you dispose of tge waste.
It is far from chemically inert.

Thanks to DuPont & frying pans, Teflon is in virtually everybody's bodies on a small but permanent scale. I used to work for DuPont.
Dump it, or better yet, mail it to DuPont in Wilmington, Delaware. It's as permanent, if not more, than radioactive waste. Its half life easily exceeds that of used plutonium. I suppose you could burn it & pollute your neighborhood air. Don't breath in that shit if you do, especially if you have dogs.
My trunk spring rollers are made from aluminum IIRC. Maybe SS.

Forget about the burning suggestion. I just took some steaks off the grill. I guess you could call that "mental association." IMHO. I wouldn't use the shit.

I like the shifter bushing idea. Maybe front and rear sway bar bushings? Rebel Racing uses it for their front and rear suspension bushings and they work great.

The 2 bushings that cradle the spring in the shifter?

What about the dogless?
OK for them to breath the dust/smoke?
Just kidding!
I have heard that overheating a Teflon coated pan absolutely kills any birds close by.
I have not witnessed this yet...
Have a 10K Macaw?
Teflons not for you!

What you have there is a large pat of butter. Leave it whole for the Paul Bunyan flapjacks.

Well,
Explains why I can pick up for nothing. Still it exists, I have a method of machining that will not create any airborne issues (cutting fluid). I do have a recycle company that accepts it.
Still pondering.
