pH neutral PVA ??!!

pH neutral

When we found information in e-shops that their PVA products were pH neutral and did not smell bad, we started to think about it. We told ourselves that we must buy such miraculous material somewhere.

As there are only mechanical and textile (and these are half mechanical anyway.... ) engineers in our company, we first asked for help our friends chemists and then our Japanese material supplier. We guessed that this problem would turn into a banality.
We handed over samples of all PVA materials we buy to the chemists. They markedly tapped their foreheads and sneered. Acidity or alkalinity – PH - can only be measured in solutions, which is not the case with PVA stockings, meshes, strings, threads, tapes or bags. Concerning bad smell, or absence of smell, I would not really believe that the noses of chemists can still smell anything...
We also “made fools of ourselves” when we asked about this our Japanese supplier. He asked us once again to verify if he had understood correctly. Then he assured us that even during carp marathons, when large quantity (that means perhaps several tens of grams....) of the PVA material gets inside the water in a pond or a lake, the pH of the water does not change as a result of using PVA!!! A change of pH value due to PVA material cannot be measured in several thousand cubic meters of water. But if the competition took place in a ten-litre bucket of a water, then the Ph could really be measured!!!! And concerning the “bad smell”, the supplier had not heard such nonsense before:-)))

There is a saying: “Why not buy it when it´s so cheap..."
