puckboard?

[sammer]

Hi all, I was in the lumber store last week and came across puckboard.
When i asked what it was i got the standard answer "they use it at the rink for boards"
Nobody there seemed to know what type of plastic it is.
I've done a bit of searching online but still not really sure.
My best guess is hdpe but thought id ask the smart people here.
Looks interesting for side walls, tip spacers or even just as a smooth surface on the bottom of a mold.
Anybody know? thanks

it's polyethylene. not sure of the density/molecular weight, but I would guess it's HDPE, though UHMW is supposed to be the substitute, according to my plastic supplier's catalogue, so Im not sure.

hdpe is the most used plastic for hockey rink dashers. uhmw can be used but is for expensive. the only real difference between the two is the strength being uhmw is the stronger material and also more expensive. industrial plastic supply is great place to get both materials.
