It it wasn't. How do you think wax is absorbed into the base material??? The idea of hot waxing is to heat the material..... opening the pores to except wax. The base cools, holding onto the wax it needs. You scrape off the excess. I accept your apology and you learned something today.
Nope, you are perpetuating an old myth. Once again, Ptex does not have pores
- none at all, zero, nada.
What Ptex does
have is an amorphous surface with lots of nooks, crannies, ridges, and little 'valleys' - this is what it looks like magnified:
And wax is not absorbed
into the base, it adheres to this surface structure.
