Recently, I've been playing with solid UHMWPE. I have no idea whether a
glider could be made of it but it's fascinating stuff - very light,
strong,
slippery and with fantastic abraision resistance. I understand it can be
injection molded.

I have two pieces of this plastic in the shelf, one, 1 1/4" round that
is assumimg a C shape slowly, after about two years, the other is
3/16" sheet that is becoming a very interesting shape after roughly
four years. Tends to indicate that over a period of years it is not
dimensionally stable, but warps. Neither of these pieces is supported
over it's length, it's on racks with similarly shaped materials.


I suppose if you have a hip replacement joint made of UHMWPE you should be
concerned. Maybe the stuff the implants are made of is somehow different.

A hip replacement isn't sitting in one position for two years at a
time.

Oh, I don't know. You should see some of the layabouts in my houshold!
