coefficient of friction for uhmw-pe

[FMorin]

I intent to use a bar of UHMW-PE as bearing for a paperboard roll(with thin metal strip rolled up on it), but can't found any references for coefficient of friction between those two. Without this, the force needed to pull the strip is ''difficult'' to calculate.

Are there any references for this coefficient of friction or anyway I can do to solve this problem?

Many thanks.

What exactly are the materials in contact? For smooth steel and PE, the dynamic COF is below 0.2 (but can vary with surface finish and speed). Recommend testing.

The materials in contact are a roller of MDF turning on a UHMW vertical bar.

I'll rather test after having a good approximation of the process.

Thanks

MDF = Medium Density Fiberboard?

Yes, thats what I've been told by my distributor.

The PE will adhesive transfer onto the MDF. You will end up measuring friction between PE & PE
