production / ethics

When I have the time I’ll find a good explainer in Performance Days from a someone who works for EU legislation on toxic chemicals - and identifying/phasing out stuff like this - which explains the chemistry behind the C8/C6, the toxicity of the PFOAs used to create them, the alternative types of C0 treatments and why they don’t perform as well.

Here's the presentation (audio) and deck

but tldr is in this screenshot, with the clear difference of Fluorinated chains being able to repel oils, whereas Fluorine-free will effectively bond with those oils. The longer the chain (C8 > C6 > C4) the more repellant and durable it is ....this is why the industry is having such a problem. Alas, all the best intentions will never beat physics.....
