"especially considering that the polypro seems to be claiming to be free of something that it isn't for whatever reason (tainted product, flat out lie.....who knows?)"

Not sure why you say that... Polypropylene is a substance. Polypropylene is an inanimate object, it can't make claims. Polypropylene is what we use, not Polycarbonate.

And since we are not using solvents such as DMSO or high heat (250C) I'm not sure what the point is.

who's to say that chemicals don't leach under vaping temps? the study certainly wasn't trying to prove or disprove anything done using standard vape temps. the point is that the plastic was leaching something that supposedly isn't there in the first place.

Polypropylene is a is a hydrocarbon chain (polymer). It is subject to breakdown from UV, heat or chemicals (or other means). The complex hydrocarbon chain can be broken and oxidation and other actions can form new compounds (that weren't there to start with). But you have to break the molecule first.

The same is true for most compounds. Water can be broken into oxygen and hydrogen. Hydrogen is explosive, but water isn't. It's much more complex in the case of a hydrocarbon polymer but the same idea, breaking a molecule apart to make something else.

so, is there a known temperature where this breakdown occurs?

Is there even a completely safe plastic which does leech anything at high temperatures?

I bet if someone took temperature readings it would solve all of this bickering. This party would need to have a GOOD instant read probe thermometer to accomplish this. To do this accurately possibly you could even drill a tiny hole for the thermometer probe all the way down to the metal at the point inside the vapor stem where the metal ends inside, this is where you would have any contact with the air path anyways.

So there's <0.1 milligrams of weight loss in the first few minutes. It'd be nice to see a detailed table of data, but oh well.

Don't suck through the stems for more than 3 minutes at a time, problem solved

Yes, nice find. Thanks.

"The degradation of P P was studied a t
temperatures close t o those of industrial processes t o
reveal the kinds of volatile products formed a n d their
concentrations under normal industrial conditions."

And these temperatures are not encountered in use with a PD. These are temperatures that melt the plastic for injection molding or forming. Our temperatures, don't reach that point, or the tubes would become deformed.

Just got a delivery of American Cherry. Always consistently great stuff from these guys. I really like the other woods they have sent to. Another small, family operation.

Not that this is really too on topic, but I'd like to add that the figure I posted is quite possibly one of the worst figures I've ever seen. But you can see from the figure there is a minute amount of weight loss at temperatures below 200C. Unfortunately since the figure is so low res, it's impossible to tell exactly how much, but at the very most it appears to be <0.1 mg

I bet the Polyproylene doesn't even reach 100 degree celsius unless someone leaves the stem inside the heat port for long periods of time.

Interesting.... Idk about .1, but the pd gets to what? almost 200C? That's about .4, and check out the time in minutes. Those temps are in the same, or less than the pd takes what 45 mins to heat up? Who isn't going to toke for more than 3 mins? I've never seen anyone toke less that than, even when combusting. So you mean to tell me that none of this happens even at low temps? Last I checked Tom stuff doesn't need to melt to produce harmful chemicals, and last I checked this isn't the it doesn't do anything until 250C? Check this out directly from Wiki

The melting of polypropylene occurs as a range, so a melting point is determined by finding the highest temperature of a differential scanning calorimetry chart. Perfectly isotactic PP has a melting point of 171 C (340 F). Commercial isotactic PP has a melting point that ranges from 160 to 166 C (320 to 331 F), depending on atactic material and crystallinity. Syndiotactic PP with a crystallinity of 30% has a melting point of 130 C (266 F).
Last I checked that was in the PD range, but again I'm probably wrong right?

http://occmed.oxfordjournals.org/cgi/content/abstract/45/2/69

Check out that and the effects of polypropylene. Cancer causing? Oh noes!

also from wiki

Degradation
Polypropylene is liable to chain degradation from exposure to heat and UV radiation such as that present in sunlight. Oxidation usually occurs at the tertiary carbon atom present in every repeat unit. A free radical is formed here, and then reacts further with oxygen, followed by chain scission to yield aldehydes and carboxylic acids. In external applications, it shows up as a network of fine cracks and crazes that become deeper and more severe with time of exposure.

For external applications, UV-absorbing additives must be used. Carbon black also provides some protection from UV attack. The polymer can also be oxidized at high temperatures, a common problem during molding operations. Anti-oxidants are normally added to prevent polymer degradation.
So it can cause crackings over time in the material as well if heated enough over time, hmmm?

It's also funny how after the whole thing with "Rick's Brass" This comes up and bites you huh? Sounds like a bad case of Karma to me, well worth it though.

Let me just throw out some more articles I found, happy reading vapists <3.

All this technical stuff is lost on me, but the thought occurred: why not just make or acquire a glass tube? I'm not really too worried about the plastic tubes though because I've built up plenty of resistance breathing the air in a forty-eight year-old school building. Of course, it's convenient for me to have this position (if I have a position on the subject at all) since I've been waiting for my PD for sixteen weeks now and smell the sweet skunk of victory on the hazy horizon.

I'm dying to immerse myself in the PD experience. Thanks for the opportunity, T & P!

KZ, beachvapor got banned because of his total disrespect for Tom as well as many of the members here. It had nothing to do with holding Tom's feet to the fire. Although I am a major fan of the PD and it is my go to vape, I have no problem with your post above and I have no doubt that Tom as well as others will counter with some of the statements made above, and to my way of thinking, it's all good in that it just helps us learn about the things that are good and bad for us, and allows all of us to make our own risk/reward decisions, much like what was done in the brass zap thread. The ONLY thing that I take issue with is you lumping yourself with beachvapor, and assuming that you will get banned for doing nothing more than raising some concerns.

The way I see it, that brass/zap thread served a very important purpose in that it educated ALL of those that read it about the dangers and safety of brass and was a catalyst in Rick making some changes to his product. I don't see any reason why we shouldn't have the same discussions about any materials used in any of the vapes on the market, be it polypro or anything else for that matter.

This whole idea that this site is PD-centric and that anyone who raises any negative concerns about the PD will get banned is just a myth, that is, as long as the discussions remains objective. It's when discussions like this becomes subjective, that problems occur.

so I've got my grinder and dry goods and so on and I came by a parcel of very fresh, green. em, I wonder if green would vape? yes it will and very nice actually, a bit green on the taste, but 4 piulls later all was gone crumbled like dry browm matter, perfect. not my style, just tried it.

What grinder are you using, just out of curiosity?

^^^ Konrad doesn't seem able to distinguish one plastic from another.

Again, as with other posts, Polycarbonate is #7 and Polypropylene is #5.

They are not the same at all and #7 is the one with the Bisphenols and all the problems with baby bottles etc... We use #5 Polypropylene. As pointed out in one of the articles it is the safe alternative to Polycarbonates. And again our Polypropylene remains relatively cool, never exposed to the temperatures discussed in those studies of industrial exposure while melting the plastics for molding.

As you can see this fellow is banned later for his behavior in other parts of this forum. He was just another forum troll, looking to stir things up for some private reason.


Yes, Flyer, I have come across 'fresh stuff' and used it in a Super Vapezilla, not so tasty, the taste of chlorophyll, but after a bit of use it dried and worked. Not my style either, but in a pinch...

+1. THIS.
Also +1 to your other statement as to the plastic not even heating up with it being left in. Who knows how much heat is actually thermally conducted through the steel shell and into the plastic. With this plastic, it's seemed to me that if it won't melt off of the steel tip, it probably won't offgas. I would guess the range of temp's where it would ONLY offgas but NOT melt to be rather small, but I could be very wrong on that.

Seriously though, it's a plastic. It can make harmful things under cetain conditions, more so than other materials. So is it compeltely safe? No. Is it most likely safe for the application at hand? It certainly seems that way, unless I find out that BPA has a very low dose/reactivity ratio. Especially in a situation such as this where a compound that is certainly harmful at temp A isn't at temp B, descretion in calling into question, and putting up informatin that counters said question, is kinda neccesary.

To all those who would question this vape, remember that from a probability standpoint, a LOT of the issues out there that could be challenged have been already. Though this doesn't mean that any point isn't worth making, it means that the people who partake in these back and forths have already addressed a billion things in terms of how and what the PD rocks, and are tired of re-visiting old topics that have a good chance of being put to rest. Let alone how Tom must feel when issues of health safety are connected to his brain-child, many feel uncomfortable with what could result in untrue rumors developing around something that is so valuable to so many. Measure your observations closely.

To all those who love this vape, (ME as well.), just look at it from the perspective of someone outside the confort circle, of someone who isn't as well learned in the actual application of the materials used. People come and go in this forum all the time, and leaving a comment about how something could be harmful is, from their perspective, something they are doing to help the community. Leaving a sarcastic reply in response in reply to a genuine one is regrettable but unavoidable sometimes on the internet, especially when you are a manufacturer dealing with what could appear to be a troll. Remember though, it takes no less effort to simply correct someone and leave some confident words as to the safety of the unit.


Let this areguement die as the Brass one did, because as with that case, BPA is only a factor at higher temps, which leaves a LOT of indisputable grey area when it comes to the lower temps. Science isn't always cut and dry, so maybe neither lead (in small Brass related concentrations) or BPA is physically a factor at all at low temps. Maybe they both release minute amounts that actually don't have an affect, as opposed to minute amounts that do. Maybe both vapes will kill all of it's users in five years.
Though I seriously doubt that last one, attaching emotions and passions to a purely scientific lack of knowledge on a subject helps no one; let information be put up without a fight, just make sure you put up your own in as large as amount as is neccesary. People are never convinced by people over the internet, only by information.


So I'm finally in the summer semester, so that means free time for exausting vape reviews! I know everyone who ever got obsessive about researching the PD has seen an excess of reviews, but I also know every vaporhead would love some wood porn :D
I'm thinking of doing a three-way with my genie and star as well, anyone know if I should post a copy here as well, or is it more kosher to leave them all in another thread in the vape-specific forum?

I've really come to like my Purple Days in the last few weeks, it grew on me a lot recently as I've started smoking less and getting back in focus with my life. Named it Domo :). Anyone know the reference?


Also fun theories as to why the PD has such a ballsy kick for such small amounts: Vapor density. Not sure if this has been talked about prior, but I've noticed that with my PD I tend to come down more quickly. This got me thinking, as I've had this to a less degree with other vapes as well,: Maybe the intense vapor density of the PD isn't more efficient as much as it concentrates the affect into a smaller range of time? It makes sense, as anyone who used to know that if you smoked even a small J you'd be cruising for a while, when if you vaped that amount you'd probably be reehaheely high. So we vape less, and achieve the same level, with (some/sometimes?) not having as long of an affect. Maybe because we vape less physical matter it doesn't last as long, and since with the PD we use even less to get just as phased it has an even steeper come down slope?
Hit this back with any thoughts, I'm curious to see what you peeps think :peace:

Welcome neilito! Seems like you might be new to the forum, and almost new to your PD experience :)

Also, some great points KZ. It's really nice to read up on the details about PPL and PCN plastics and what happens to them under certain temp conditions. That being said, make sure to edit out things like the second to last link, which only questions PolyCarboNate, with PPL being advocated as safe. Some great info in any case, keep it coming :peace:

I have two PD's. A cherry that vapes at a pretty high temp and an ash that vapes at a lower temp and what I have noticed is that the high last longer with the cherry than it does with the ash.

You seem to be under the impression that the polypropylene tube is inserted directly into the heat exchanger. This is not the case.

Please review our forum rules. Material safety discussions belong in General Discussion, not in a model thread. Posting for the purpose of disrupting the community is also not allowed. You are free to dislike Tom and the PD, but acting on that, especially in this thread, is not going to fly. It's pretty clear that this is your intention. Next time will be an infraction.

For the record, beachvaper was not banned. They would have received an infraction for breaking the rules, but since they stated "Don't worry, I'm out of here for good. Insult away egomaniac and groupies!" the door was closed for them. I fucking hate swan songs.

Repeating: Material safety discussions belong in General Discussion NOT in a model thread.

jeffp, sorry, I have been struggling with a grinder since day one, like which on, i by passed the grinder that particular day to try this little run away freshy bud on the counter, so I stuffed into a stem and hit away, it works, it is ok probably will not do it any more. I did no grind a thing this time, just stuffed it in, pretty damp. the grinder I did settle on is from a high end food/ kitchen store. it is made as a herb grinder, remind you of a small farm tool:lol:. I am trying to get another one for a member here also, they are out.

I've always liked that aspect of wooden vapes, that different types yield different results. A neat little quirk of the genre, one that seems to be practical too.
The other nights I re-assessed my packing methods to great reward, which does decrease the validity of my theory. With my old, light packing method I got great rips, but got exponentially more with a tighter pack. Must be a quality of the airpath :ko:
Still feel like I'm feeling out the purple days "flight-times" if you know what I mean, but I think it might level out with experience. Love the learning process with my little buddy haha

Yeah. Different woods, because of their density, will provide different vape temps and is the main reason why I have the ash along with the cherry. I can get what each one has to offer without sacrificing efficiency by going to another type/brand of vape.

I love my cherry unit, but I've yet to completely brown a load, which confuses me. I'm high as a kite every time, but still with no toasty abv when i pull the stem. I've wondered from time to time though if my campus's wiring is just shitting the bed...
