NinetyFourThe smooth side of the base material isn't meant to be the final sliding surface. That's just how it comes from the manufacturer. After the ski is pressed, that smooth side is sanded and structured so it can better accept wax, and negate a suction that a ski can create while sliding.
rozboonUHMW HDPE doesn't absorb wax, so you can forget about that aspect for a start.
Essentially it's just a piece of (usually) sintered plastic with a structure ground into it.
parkplaygroundsintered bases actually do absorb wax since there are very small pores that are created from the pressing of the base (sintered bases usually start off as a powder if I remember correctly). It is not on the level of a sponge obviously. I guess its technically not absorbing it, rather the wax fills in the pores and makes contact with the snow instead of the base material itself (from my understanding). If anyone who understands this more or knows the exact science behind this, feel free to show me up.
so yea, I didn't need to post since the quote said that
rozboonThis is a commonly held skiing myth. A molecule of your average ski wax is considerably larger than the intermolecular spaces in a sintered ski base.
This has all been hashed out on here before, but see this study:
There are SEM photos of base material on pages 19, 20, 21... they show that waxing (as a process) does smooth out the imperfections in the base, improving glide, but the actual coating of wax on the base is pure film adhesion and pretty minimal, as in it's gone within a few runs on hard snow. However it's still totally worth doing if you're like, a racer or something.
tom.WhistlerBut it (the UHMW) is treated in some way to better absorb wax isn't it. I couldn't just take a "regular" piece of UHMW, grind it down and wax it, could I?
Any thoughts, if not I'll just go and try it.
tom.WhistlerThanks for all the comments, I didn't mean to re-hash the bases absorbs-wax/ doesn't absorb wax debate, so let me re-word my question
Will a ground piece of HDPE after being waxed (in the usual manner) perform like any other ski base?
This seams to be what Rozboon is saying, is this the general consensus?
