Friction Levels Of Raw Vs Coloured PTFE
Friction Levels Of Raw Vs Coloured PTFE
(OP)
Hi,
This may seem like a "just google it" type of question (I thought it was myself), but it wasn't as easy as I thought to get a simple answer. I would greatly appreciate any input.
I'm developing a product that utilises PTFE/Teflon to limit the amount of friction when in contact with skin/nail.
At this point, please keep in mind that I have zero engineering experience, so I apologise in advance if the answer is very obvious.
The original plan was to use raw PTFE for the product, however, having the option to switch to coloured PTFE (such as what you will commonly see used for PTFE seal tape) would be fantastic.
I assume switching to coloured PTFE will negatively impact its low friction properties and thus make it less effective for my application.
Assuming the above is correct, where might I be able to find exactly the difference in friction levels between raw PTFE and coloured?
If the difference is relatively minor, it will most likely be worthwhile switching to coloured for aesthetics.
Thank you for reading.

You'll need to create samples and test them if the friction level is critical.

I only mentioned sealing tape as an example of the colouration that I had in mind, apologises for any confusion. If coloured PTFE has similar enough properties to raw PTFE in terms of levels of friction under the conditions above, I would simply have the PTFE part carved out of a coloured PTFE block rather than raw.
Thank you for your input, Dave. Continuous load and abrasion shouldn't be an issue, the PTFE part will only have 60-90g of pressure applied for a few minutes at a time. I hadn't considered UHMWPE, I will do some research on the material.
