But that's untreated. Then what? As I understand, you should not use untreated ceramic sleeve, it can make you sick.
Agreed. It's been discussed extensively on various threads here. I had a substantial legacy supply from BTV I have used for five months now extensively conducting wicking tests on a variety of atomizer form factors, resistances and coil config's across the spectrum. It is an amazing wicking medium. I cannot attest or comment pertaining the safety aspects of the latter either. I've seen little beyond anecdotal postings regarding anything less than the 3M recommended stabilization process. Presumably, the physical nature or attributes (pliability,
threadability) of
heat treated and
heat cleaned material differ substantially. The latter becoming stiffer and more manageable for winding, perhaps insertion of certain other wicking materials like mesh or ceramic. However, it becomes utterly useless for wicking material if you intend to thread it as it
splays or de-braids instantly on cutting. I believe, not having participated in either process that simple heat clean is augmented by torching; and that
this more than anything changes the normally flexible characteristic of the wick to an overt stiffness. Even brief torching will destroy the braid flexibility of virgin unprocessed Nextel.
What I can attest to is that presumptively
heat treated XC-132 is an exceptional wick for closed tank atomizers requiring miniature or micro coils. Personally, except for dry hits I encounter routinely in the voluminous build tests I do, I have suffered not at all with use of the Nextel wick as opposed to silica. Nextel inserts effortlessly into a coil with rotation pressure in the direction of rotation of the wind. It is intuitively simple to use even for the uninitiated, and outstanding in performance even when winds are sloppy. As a dripper media though it lacks the saturation of Ekowool; but, it's ability to flow is incredible. It will drain your dripper quickly producing abundant flavor in the process; but, for most builds in my experience not as abundant a flavor
with vapor output as silica, Ekowool and certainly not cotton. It's advantage is remarkable durability and ease of maintenance. SnG's excellent torching video is spectacular to see (on their website) and I commend them for their education on this matter.
But please all note here very carefully, at present it is unclear whether either of the two present vendors (SnG, RBA) intend to carry or deliver an XC-132 product that does not splay when cut (presumably
heat treated). I have been in the process of discussions with owners of both firms and they appear receptive and responsive. Their cooperation is appreciated. However, as of this date I have not seen a final product (or commitment) that would seem to conform to that requirement. In the case of RBA, to resume their offering (as I seem to recall they had it briefly at the outset of their operation).
I continue hopefully more encouraging conversations this morning as they both are available.
Wish
us luck.
Happy Holidays all.
