Non burnable wicking?

[ScottP]

I was just wondering if anyone has tried to use Kevlar or Nomex type thread to make extreme heat resistant wicking material to prevent burning.

Hi Scott. Many folks use fiberglass which is very burn resistant. In fact the burning most people associate with wicks is actually the gunk that collects on the coil and not the wicks at all. Everything that I have that has wicks gets dry burned at high voltage to clean the coil and wicks. They also get vaped at high voltage . Burning is most likely the flavoringsin the liquid or the buiildup around the coil.

But I like whaere your thought process is going. Yes nomex has been used to cover the stinless wicks in some folks genesis atomizers to prevent hot spots ..... kevlar I have not seen but I'm sure that somone has tried it ... Sounds like it time to get searching....

Well Nomex has a higher temperature tolerance than Kevlar so if Nomex has already been used then there is not much point in trying Kevlar.

I have heard about something called "Alumina Thread" which is apparently a ceramic fiber thread rated at 2200F (3992C) Continuous exposure. If that isn't burn proof I don't know what is. I am not sure how that would work as a wick though.

I started along this train of thought thinking of ways to make our parts last longer between rebuilds or replacements. Then again like you say if the "burn" is from the juice and not the actual materials then this may not be what is needed.

Still worth considering. I'm using cotton now because the little fibers in the silica worry me. Does fiberglass have the same problem?

The whole concept of fiberglass wicks seems bizarre to me, I keep thinking "motorboat"

If you have any of the nomex or kevlar wick how does it compare to silica for flexibility? Is it as fragile as ceramic?
