Shan...that looks like fiberglass the way it explodes and frays when cut..

@42109...I would not use fiberglass IMO...dunno about the candle stuff.
Well it sure looks like all the Germans use fiberglass.

I can't get nice long strands like that from the silica rope I bought.



Looks like long, smooth, strands.

Hey Shan B,

I'd like to try that yarn, see if can find some small quantities.

WillyB I keep coming back to this: Umgang mit Glasfaserdochten

Only shop I have found so far is Bulli Smokers: Glasfaser Für A1-Verdampfer

The stuff in the pictures above that looks like hair they refer to as Ofenschnur which basically is Oven Rope/Stove Rope/Sealing Rope/etc. Made from Glass/Fibreglass.

The best thing I can think of trying which is similar to the above is something like para-aramid, like what fire-eaters use. Says here that is is commonly called Kevlar or Twaron.

Yup. but there seems to so be much resistance here to 'fiberglass'.

Your link to Bulli's German site was interesting, I've only perused the English one which is much less detailed (no wick picture or A2). Bulli seems to now be using a braided wick very similar to the CE2 one.

Trying to get the silica I have into a neat stiff loop that will stand upright is tough.

I did find this from you link, seems very promising. The top down approach for liquid seems like a better way than the standard carto's, from the bottom approach.

To be able to quickly swap out gunked coils for mere pennies sounds like winner. Tinkering is fun, but the clean looks of the A2 is beyond my skill set. I'll be waiting for a price.

Not sure if I edited my post after you posted WillyB, but I do believe that they may be using Kevlar/Twaron which from what I can see looks almost identical to the pictures above. It makes sense when you read into it, Kevlar looks like the ideal material for atomisers.

-edit

Yeah that A2 looks pretty clever, being able to easily change the coil/wick seems like the way forward. The A1 appears to do the same thing just without the standard fittings meaning you would have to buy his proprietary e-cig which is around 100 euros. I guess we can assume the 510 A2 will be around 50 euros as it isn't that much different from the A1.

Does anyone know what the wicking in commercial atomizers is actually made of? I ran across a Wikipedia article on asbestos with a picture of asbestos fibers that look just like the wicking in an atomizer. I also looked at silica fibers and fiberglass, which is made from silica fibers. All these materials closely resemble each other and have similar origins and properties.

Silicosis is a disease caused by silica fibers embedding in the air sacs of the lungs and causing irritation and growths as the lungs grow tissue around the irritation to encapsulate the intruding fiber.

I'm not pushing scare tactics here, just looking for opinions. I don't think that tiny fibers are a huge concern in Ecigs due to the wet nature of the operation of the device. It does cause me to wonder what doesn't burn and decompose when a red hot coil (dry burn) is wrapped around a bundle of these fibers and whether long term use could be an issue.


From this link: Fiberglass - Wikipedia, the free encyclopedia
Safety

Fiberglass has increased in popularity since the discovery that asbestos causes cancer and its subsequent removal from most products. However, the safety of fiberglass is also being called into question, as research shows that the composition of this material (asbestos and fiberglass are both silicate fibers) causes similar toxicity as asbestos

Maybe this will help DaveP: HEALTH EFFECTS OF MAN-MADE FIBRES

Kevlar para-aramid which I posted a photo of earlier states:
There are no studies available regarding the human health effects of exposure to Kevlar para-aramid fibre. However, in view of the evidence of decreased biopersistence and given the physical structure of Kevlar, the health risks should be minimal if exposures to fibrils are maintained at 0.5 f/ml or less, as is now the case in commercial applications

I am not sure if Kevlar is silica although it does look the same. I think that is the issue here, a lot of stuff referred to as fibre/fibreglass/glass doesn't necessarily mean they are all made in the same way as each other with the same materials. So how they react to the heating coil and such will be different for each one etc.

I agree with your point though, in commercial atomisers we should really be told what they are using.

Sorry to res a two month old thread, but would this: Kevlar Cord possibly work for a wick? And at $0.20 a foot, not a bad price at all.

Kevlar doesn't burn, handles 900F before it disintegrates, and holds liquid quite nicely. It's mainly used for fire eaters and other flame toys...

I'm tired of burnt tasting wicks, and I'm planning on ripping apart a few old burned-taste atomizers soon to build my own, and I want a wick that will last and not burn.

Anyone have experience with this material?

i know im a little late on this thread but anyone ever try ceramic rope as a wick? i was about to order some silica and will probly get some ceramic as well.

Don't know if this will help ya.

Ceramic fiber textiles (cloth, tape and rope) contain a certain amount of binder material which is normally burned at lower temperature and does not affect the insulation

Looks like the binder may be a problem.

Hey Zombienerd,

Have you tried the kevlar cord for wicking material yet? I think I'm gonna buy some from McMaster-Carr. #3 McMaster-Carr Its max heat is +2300° F. Just curious if you've replaced any of your wicks in your ego-t's successfully. thanks

Bumping and old thread here to find out the same. Has anyone used the kevlar cord? 5 feet is less than $4 delivered and could be a much better alternative to fiberglass or silica. I may order some anyway.

I decided against the kevlar cord since it seems to break down and off gas at high temps - a dry burn would probably kill it. So I'm back to thinking Silica from McMaster is probably the best choice, Silicosis not withstanding.

I went ahead and ordered some of the kevlar to see what its like. I'll report back with the results.
