Teflon contact material with highest Co-ef of friction (D&S)
Teflon contact material with highest Co-ef of friction (D&S)
(OP)
Hi all,
Im looking for a material with a high (relative to teflon on steel) co efficient of friction on teflon.
I have managed to find (google)
0.04 steel-teflon
0.44 brass-teflon
0.24 Aluminium-Teflon
but i would like some more options and i am unsure of the accuracy of the above results.
Material chosen will be used in a push/feed wheel for teflon tubing which must rely on friction to function. I would prefer not to have to knurl the wheel so the co-ef of friction will be critical.
It will also have to feed exact lengths of teflon so will be stopping and starting a lot.
Any recommendations?
Thanks in advance

You may still be screwed.
Try to strip some teflon-insulated wire.
Note how you need three wraps around something to keep it from sliding.

You are probably referring to PTFE. Just wanted to give you a heads-up so that you can make sure the numbers you are using are the right ones, i.e. that they really do apply to PTFE and not some completely different polymer.

Any durable material will do or likewise a non chemically applied coating/layer (Mechanically secured) on a different base material would do
Im trying to keep the solution as simple as possible.
