So what is the consensus on the whole off gassing problem? I ordered one the other day and found out about that problem only recently. My davinci has not arrived yet but I am worried to even consider the vape, I don't want burnt plastic going into my lungs......
Nobody has had any problems with
burnt plastic. Nobody. Burning is something entirely different.
The rubber used is a polymer. A jumble of long molecules tangled up like a plate of spaghetti. A liquid. In the processing a catalyst is added to such stuff to 'cross link' the molecules to make a mat that's more or less solid (like that plate of spaghetti when it gets cold). After it sets up the catalyst has to go somewhere, it migrates out through the material (or you'd never smell or see it....), like the 'rubber smell' from new tennis shoes. Temperature and time (in some processes vacuum) speed this stuff along. This is called 'curing' in the trade. If it's 'food grade' care is made in the selection of the catalysts used for this reason.
So many of us found we could see 'mystery vapor' (as someone called it, it's no mystery really, we know what it is) from our new DVs with empty bowls. This gets less and less as the material near the surface migrates out, you need higher and higher temperatures to find it. Dropping down in temperature from 'full blast' basically stops it as you might guess.
Another factor comes into play as well. Condensed vapor ends up sealing the surface so the catalyst can't evaporate that way any more so migrate through the material and out the other way, away from the vapor path.
You noticed how the rubber smell left your Adidas over time? Same deal, only being as this is food grade there's really no health hazard.....like there is with the tennis shoes.
This 'toxic hazard' caused a big stir in the Puffit thread as well. Well intentioned folks got into "carcinogens" and all sorts of wild concerns.....IMO ended up scaring the women and horses as the saying goes.
Lots of good info on the web on the topic. NASA did some very useful and interesting studies on this topic a while back. IMO the risks are trivial compared to blazing for instance?
