I can't get your reference to open.
But yeah, the way I understand it the "pores" idea is a low-resolution analogy.
I read a good paper on one of the wax company sites that explains it a lot better.
P-Tex is a hydrocarbon, and wax is hydrocarbon, so it (loosely speaking, I am not a chemist) dissolves into the P-Tex.
Not really a mechanical filling-in at all.
The magic of flouro waxes apparently is they have molecular chains whichN are hydro-carbon on one end, so are compatible with the P-Tex, and stand-offish flouride-family chemicals on the other, so they stick out and repel everything, or dissipate static electricity, or something.
Speaking from memory, I've lost the copy of the paper with the explanation, and IANAC.
Yes. I keep reading about pores in P-Tex opening up with heat and absorbing wax. In fact, the claim is made that new skis will continue to absorb wax over dozens (?) of applications prior to use. It just doesn't seem to make sense that a product as dense as HDPE would act as some kind of wax sponge. Imagine how heavy those bases would become with all the wax in them from multiple applications. And then how does this wax get released; if it's truly in pores in can't be scraped out, and it isn't melting out. And what good it wax locked inside the structure of a ski base?
I can imagine that molten wax may be adhering to the base surface and filling in the irregularities in the structure. Micro scratches, grooves and pits could get filled in and make for a smother sliding surface after the excess is scraped off. This would make sense with the theory mdf is referencing. But pores?
I guess I was imaging that if pores do exist, someone would have a cool HD image from an electron microscope showing them opening with heat appication and drawing in molten wax. That would be good definitive proof. Otherwise, I have to believe these pores are just an myth. (I'm not saying that the benefits of wax application is a myth, just that the existence of pores in P-Tex is?)
