Pepermint disolved plastic tank ! ( fast).

[Tangaroav]

I received my Kayfun Lite Styled Rebuildable Atomizer (20ml), Fastech item 1733905 a few days ago. I installed a coil, 1.5 ohm and filled it with my regular pepermint e-juice. Within 1 hour of vaping, I could no longer stand the chemical taste. I drain the unit, clean it and see below what the polycarbonate tank looked like.

It was being disolved, fast ! My pepermint e-juice is made with TFA, (the flavor apprentice), perpermint only. I sent a ticket to fasttech. They were very responsive and offered to replace the tank.

I think I just learned that pepermint IS a polycarbonate tank killer. Maybe I should have read the tank cracker threads with more attention.

Too bad, because that 20ml volume is really interesting. This is a 30mm RBA, it looks great and at a great price.

edit: I just found out fasttech has the same model with a SS tank. No. 1744005 . I ordered one ! ( and requested Fastech to replace the plastic tank with a ss model.​

yup. that's why plastic is dumb. I wish manufacturers would stop cheaping out and move away from polycarbonate and pmma already. borosilicate/pyrex is where it's at and atomizers should incorporate glass into their design.

Uhh..... 20 ml? That must be the size of a light saber!!! Most kayfuns are 4 or less...

when you consider that the same juice will degrade the orings that are used to hold in that glass, then maybe its the juice makers we should be looking at...

food for thought.

Yes rubber or silicone orings are another concern; I wouldn't look at it as a juice problem. The same problem occurs with the food that you eat; that is why we eat generally on stone and glass and not with plastic; it's not a matter of 'style' or fancyness; it is pure practicality.

our stomach can ingest such acidic things, our lungs on the other hand, i dont know...

I'm not a doctor, and am not claiming anything here, just using common sense.

if it is so acidic that it can dissolve plastic.. should i be breathing it in?

i came to this thought after having inhaled Pluid for long a time......

lets just say... i now DIY

First of all, are you using the word 'acidic' loosely? Or do you specifically mean acidic in the chemistry sense?
Perhaps 'corrosive' is the intended meaning.

Plastics are organic compounds.
The human body like all other lifeforms that we know off is based on organic compounds.
Organic compounds refers to the CARBON atom; the chemistry of both plastics and lifeforms is based on carbon chains.

It's not surprising that organic compounds that we might ingest for whatever reason, reacts chemically with plastics.

Stone and glass are basically silica substances; inorganic in nature; few things that we would be interested in ingesting will react with silica.

Hydroflouric acid is one of the few compounds that dissolves alot of things; i think its stored in plastic because it would disolve a glass container!

I havent had any problems with food-grade silicone o-rings (the red/orange ones).

where do/did you get them and how did you know they were supposed to be food grade?

Worked with this stuff before, quite nasty I must say. Used to etch glass in industrial applications, also "pickles" stainless steel, which gives it an odd greenish discoloration where its applied. Is capable of fusing your joints with prolonged exposure.

In this case I was using a TFA pepermint flavor, (10%) and the usual base liquids. The same e-huice that I vape very often with my other RBA's Clearos and carto tanks (They are all pirex/glass). I never had any problems with 0 rings.

I sure will never again use plastic tanks and I agree that plastic should be banned. The chemical taste was very bad. Before it got too bad I thought it was because I did not wash the new RBA before using....

Darnit. I have 20ml of TFA peppermint, was planning on makign some juice with it and I use plastic clearos. Burn that idea, I guess.
