Every generation has some product/ingredient that they didn’t know was dangerous at the time: tobacco, lead, asbestos, etc. What is that item for this generation? (lemmy.world)

PTFE is dangerous?

[–] [email protected] 9 points 1 year ago (4 children)

Who knows! https://en.wikipedia.org/wiki/Polytetrafluoroethylene#Safety

I'm not qualified to assess this. I am just aware of the fact that if a company can trade my personal health or the health of the environment and ecosystem for a profit, they will do so. Whether it's fighting regulations for safer trains that carry hazardous chemicals, conducting studies and then promoting a campaign to fight its own findings, or dumping chemicals they already know are hazardous but unregulated, or maybe you will add lead to gasoline to prevent knocking in car engines just because you can sell it better. These people will lie and lie and lie and lie.

So is PTFE dangerous? I just have to assume it is. I don't know.

Well, that's not ideal, my 3D printer has some PTFE tubing and while I mostly print at maximum of 250˚C, there are some materials I wanted to try that need larger temperatures. Thanks for the info!

I assume the tubing part is the Bowden tube? I don't think that will become much warmer than ambient temp.

Yep, but it's really easy to mess up and make it touch the really hot parts.
