I had high hopes for this stuff. Ordered UHMW polyethylene tube part number 8705K141 from McMaster-Carr. Banged it on the end of a bolt and it left marks on the tube. So the high impact resistance is relative to HDPE polyethylene, fine. I read that you can't drive a nail through it. I drove a nail through it several times with no problem. Then I read it's supposed to be 15 times more abrasion resistant than carbon steel. So I put it on a smooth concrete driveway and laid a brick on top of it. Pushed back and forth in the tube slid on the driveway. Pick up the tube and noticed lots of abrasion. So what do they mean by "more abrasion resistant than carbon steel"? Does that mean like if you rub it with your thumb for
15 million years it will last longer than carbon steel would? Are they using a narrow definition of "abrasion resistant" and "outlast"?Thanks for any translation of what they're talking about.
