Peek Toxicity

[Scy123]

On my krakens I like to build low ohms and chain vape it. It works really nice for that. Only problem I have is the insulator melting after awhile. I'm not sure what plastic they use in the kraken clones but they seem really prone to melting. I've melted 2 of them, a fasttech clone and a hcigar clone.

I searched around for a more heat resistant insulator material and came upon PEEK. It has twice the melting point of Delrin! I could not find anyone selling peek insulators but found it easy enough to make my own out of 5mm PEEK rods.

My only concern is the toxicity of PEEK. I searched around and I seems like PEEK has low toxicity. I was wondering if anyone knows otherwise.

I don't own a Kraken, but wondered about what could melt the insulator without getting into heat ranges that create some nasty and dangerous chemicals.

If you are melting insulators you may be operating outside the specs of the device. I haven't melted the insulator on my Kayfun yet, but I vape at 4.5v or under and only dry burn a couple of times a week when I change wicks.

What's creating the heat?

Here's a short thread with some information.

I think the thing with the kraken is that the coils are right beside the insulator. I also like to dry burn the hell out of it when changing flavors.

See the white thing around the center post that is the insulator. it's pretty much almost touching the coil screws.

I think the standard insulators in there are some variation of teflon... I could be wrong on that.
Peek on the other hand is an excellent material. We use it in many of our products (I work at a manufacturing facility for oil field equipment).
If you have the ability to make your own insulators, I would highly recommend peek as a medium of choice. Low toxicity, easy to work with, scorches long before it melts...

Anyway, that's my
