was wondering if the discussion was ever settled whether or not its ok to use blue foam, anyone here been using blue foam in a 510 for a while?

I've been using blue foam for my eGo carts and it works beautifully. I read a few posts around here (can't find them now) about blue foam so allow me to paraphrase:
Blue foam was recommended because it's used as an aquarium filter. Fish are by far more sensitive than humans, and if it won't harm a fish, it won't harm you.

Blue foam is perfectly ok at the temps we vape at, especially so because it's kept wet or at least it should be.
Love blue foam. Works perfect at normal voltage. As always, gotta keep it wet. When i use it ill use highping's strat of making a plug with it. Works as well as any cart mod ive tried and best of all its really easy. 
I have found that between my 510 and M401, that the foam works far better for me with my 510, yet the polyfill works best for the 401, I don't think that either are dangerous, but I think its still recommended to replace it every few weeks since I read here somewhere that the material does break down after a period of being filled with juice.
Don't think so...just left to everyone's personal decision. Many users of blue foam (maybe most) probably don't know anything about it at all, I would imagine. Often in a brand new arena such as e-cigs, you start "hot-rodding" and improvising, and start using materials in places they shouldn't be...such is the case with blue foam.
This particular polyurethane foam was designed specifically for aquarium filters, and related chemically to the infamous polyurethane foam used in construction, mattresses, etc...also called "fatal foam" and "solid gasoline" by firefighters.
According to a previous thread, blue foam releases cyanide at 500F. While it doesn't get that hot in carts, the vaporizing chamber in the atty does, and blue foam particles could get in there. I choose not to chance it, and I choose not to recommend it to new members. I grew up with mercury in my tooth fillings, lead in my paint, asbestos in my floor tiles, ceiling panels, and hair dryers...all deemed harmless at that time. Now, I don't want blue foam in my e-cig.

Members should do their own research after reading this and then make their own personal decision. Is it worth the risk? Especially since there are other cart mods that work just as well, perhaps better then the BFM.

Polyurethane is very innocuous in a normal environment...I would guess you could probably chew on it without ill effects. Polyurethane becomes unstable and toxic when it starts breaking down with heat. Polyester (polyfil), on the other hand, does not produce toxic fumes. Like I mentioned, when you improvise, sometimes stuff gets used where it shouldn't be.
So whoever it was that "recommended" BF did so based on a very flawed analogy.
I just changed all my 510 carts to ZFM from Blue foam and polyfill. All three work a treat and no leaking! thanks for posting that link Shaka (and to ego and scottyballs from that thread)
Yikes! This type of thing is exactly what I've been worrying about when considering the switch. Currently, I'm using the PTB carts. I brought up the heat point during a conversation with my husband a day or so ago. I mean, aquarium filter foam is safe for fish, but OTOH, it doesn't exactly get hot in that application.Guess I'll wait till the jury's in on this one. Better safe than sorry, after all.
Please don't take this wrong but I think that is an Extremely Silly Analogy.
Blue foam is designed to filter Water at low temperatures. The last I checked, fish dont do well swimming in Nicotine e-Juice chucked full of chemical flavoring and colorings.
Well, it is the ONLY thing I have found that will keep my eGo MEGA carts from leaking 2ml of juice all over me.
I am going to keep with it. The fact is, things are only dangerous and cause problems after the FDA says it does, just like e-cigs are inherently bad for our health anyway because big pharmaceutical says it is, I am sure the blue foam is also.
I am not sure I am going to throw away my $20 atomizers because the ONLY way to make them stop leaking is to use Blue Foam.

I'd like to know what your source is for saying that the atty chamber gets to 500F...
the infamous FDA tests put operating temperatures at between 40-60C...
and personal tests with a temperature probe hooked to a DMM put the temperature directly on the coil of a 510 atty at 180F after holding the button down for 10 seconds continuous (and that's a dry atty which would be hotter than one with juice)...
the same test repeated swapping out the stock 510 battery with a 3.7V mod and a LR atty put the temp at 275F at 15 seconds continuous firing...
SO....I'd really like you to substantiate that over 500F temperature inside an atty chamber comment..
it just doesn't in our application, or at least there's been no proof that it does...so that's what I'm asking for is his source for that statement...if you're going to make a statement that points to a possible percieved danger, I'd like to see your source or else I reguard it as spreading misinformation
Shaka I don't like you anymore! I love my B F D mod, I stopped looking into blue foam once I found it. I've been using and swearing by it for better than a month now! Guess I gotta try the ZFM I've actually got a bunch someone sent me, but man I hate change!
I've been using the same one forever, and doubt I'm getting particles, but I'm not chancing it after hearing that. Anything I need to know about the ZFM before I get hooked on it? Or I guess I'll just become found of it and in a month find out something bad

Ok I'm feeling better now. Man 180F sounds low, as much as 500F sounds high. Not questioning just saying.
right?...I know....I was questioning it myself when I got the numbers from the FDA report that said 40 -65C ....but those were for Njoy and SE....
and got into this discussion once before....so knowing that the stock 510 runs the hottest as far as stock goes I tested it myself with a temperature probe on a DMM...directly on the coil and held the button til cut off... worst it got was 180F...so only about 40F hotter than the 60C (140F) number the FDA settled on...
But given that it was stock 510 I had to see for myself going further to the worst case senario using a LR 510 on a true 3.7V battery that didn't have a cut off...which was significantly hotter but no where approaching 500F...and those were new dry atties (the addition of juice would keep them even cooler)
