Has anyone used UHMW polyethylene rod?

Just wondering if anyone used UHMW polyethylene rod as butcap or joint material? States that it is often referred to as the world’s toughest polymer. UHMW is a linear high density polyethylene which has high abrasion resistance as well as high impact strength. Wondering if it machines well and will take clear. Also, what is the pros and cons of linen based grade phenolic vs canvas grade?

I always thought it was another name for Delrin.
 
UHMW is softer, does not machine as well as delrin. glue doesnt stick to it either...machinists might chime in and tell you more.

would never use it for a joint
 
I've got both in sheet stock. UHMW is clearly softer than Delrin, but it will hold a tapped thread pretty well. I can't imagine that it machines as nicely as Delrin, but I've never tried. Too bad Delrin won't hold a finish coat or stick to any kind of glue - with the right speeds, you can turn a pretty nice finish on it - I have used Delrin rod (white and black) for collets.

Chris is right about the names.

My 2 cents,

My bad .
Btw, even if these materials do not glue, threading them makes them work as buttplates.
If they don't hold your finish, just make them a tad oversized to blend with the finish part of the cue.

UHMWPE machines well I think.Much easier to macne nicely and get a good finish compared to say nylon.Just use sharp tools with not too much surface speed.100 m/min 325 ft/min.
Like alot of plastics, it's ability to hold finish is not the best.
It is not as hard as aceytel, but has really good wear resistance for industrial parts and is really good for continual impact. eg plastic hammer face inserts.
It can be printed with plastic print inks.But they are not compatible with other materials we make cues from.
I am not sure of it's size stability with respect to moisture.
