Update:
I have been "burning off" the davinci for the past week a few hours a day. I set the unit to 430F and turn on the heater every 10 minutes. There seems to be less vapor emitting but it is still there. Although I still suspect the polyimide tape or its adhesive is the source of some of the rubbery vapor/smell, it also may be coming from the rubbery paint. I noticed when the unit was new the paint was perfect, very smooth, no defects. I am now noticing around the vent grid on the side and around the chamber on top where the unit is filled, the paint has warped and started to wrinkle up a bit. The left side of the unit(from the front) is still perfectly smooth, no defect. I am not sure if the front and back half are the same material/paint, but the warping seams to be more on the front piece of the unit.
I called Karma and they said that the different colors do have different compositions. I had a black one, they suggested I try the gray. They are sending it out today and are doing a "burn in" before they send it out. I really hope it was just a defective unit.
The opened unit clearly shows the high temp insulation over the plastic coated wires. What do you think is happening to that plastic once the high temp insulation heats up and the temperature of that plastic gets up to about 250 degrees F?
Yes, this is a very valid concern. The clear coating may be silicone but the insulation probably isn't. This same effect may be heating the black silicone ring on top of the chamber and causing the paint to get to hot and out-gas?
Manufacturer: What is the red and black insulation made of on the wires used?
That vapor you see could just be hot air with no foul compounds that may harm you..
My Volcano gives off hot air, it is completely invisible and has no smell what so ever. This is not just hot air.
I've used 2 different units and the only bad smell or taste I've experienced is at the end of the bowl, and that's ABV taste.
Have you had any experience with a clean unit? As I stated earlier ABV taste can very effectively mask the rubbery smell. I didn't detect it the first day when I used lightly with material. What color were the units?
But since more than half of your posts here on the forum are claiming toxic materials for various models, not surprising.
Seems to be to be concerned about heath, as are many MMJ patients. Even if this is another manufacturer or something, the information is welcomed, minus the claim that it is for sure the "plastic tape."
We still have a rule here about discussion of materials in a vape thread. Let's quit the speculation and comments about smelling something burning that's nobody's previously reported, and let DaVinci supply some info. Meanwhile anyone insisting on getting on a soapbox may just find their post subtracted and an infraction added.
Although I do agree on not having a materials discussion hijack a product thread, any information on possible materials safety specifically related to the product being discussed needs to be in this thread for everyone reading it to see. And my claim has been previously reported in this thread. The question is, as you have stated in some of your posted on this forum, how much toxin is acceptable. Each person will have different limits. I'm sure some on here don't care if the unit off-gasses while others will in no way stand for even the possibility of such an issue.
