Now I am going to tell you more about some interesting types of plastic and which substance was banned. Spoiler: it is a pink dental plastic filling.
TLDR for this video. No mention was made of a banned substance, nor was any explanation offered. Saved almost 20 minutes of your life.
Appreciate it. I would have kept looking. That said, it is an interesting video despite being a mite clickbaity
I thought the same thing, but I'm _pretty sure_ that it's the pink polymer at the middle of the video, which was mentioned to be used in dentistry, but had ceased being used due to formaldehyde being toxic... Thus, I took that as implying it was ""banned for dental use"". Admittedly, there's some details missing that could've made for a bit better understanding, but it's not a waste of time to watch it 😉
@@DUKE_of_RAMBLE At one point I thought the video was going to mention that Teflon was banned in cookware.
@@laurendoe168 ha! Yes, he _was_ all over the place, wasn't he... 🥴 That certainly would've been the traditional way to setup a video... - Relevant lead-in segment - Informational history - Closing outro that ties in with video title I suppose his approach *does* ensure someone watches the entire thing, huh? lol
@@DUKE_of_RAMBLE I CAN understand spending the opening explaining some of the details so that when this substance is revealed, it's easy to understand why it was banned. This is why I did watch the whole video, and walked away disappointed. YES, it was an entertaining video... but not what it claimed to be.
I officially nominate you scientific ventriloquist of the year. All kidding aside, love the channel.

DON'T DO THAT!! He could destroy a whole city block with a McD's Happy Meal and 2 napkins!! {0.o}
DONT BOTHER WATCHING FOR BANNED SUBSTANCE IT WAS CLICK-BAIT.
13:57 Translation of his shirt: "so let's figure it out" "что ж давайте расбиратьса"
Photo-activated polymerisation of polyacetylenes found in the sap of relatives of ginseng and ivy called _Chengiopanax sciadophylloides, Dendropanax trifidus_ and _Gamblea innovans_ was used in old Japan to produce a polymer resin coating on steel to protect armour from rust.
The laquer tree is definitely one of the sources too. All have something in common: urushiol. A very interesting natural resin, that happens to be quite nasty for the skin until fully cured.
DONT BOTHER WATCHING FOR BANNED SUBSTANCE IT WAS CLICK-BAIT.
This finish you're referring to is actually still practiced, but is a lost art when it comes to the European version. In Japan, these trees are well known to be the source for the resin, and the obvious source for the process of Japanning. However European replications of this technique did not involve these trees (as far as is able to be determined from reviewing genuine examples of period made European style japanning), and is still lost to this day. I'm one of many people trying to recreate the European process specifically to reapply it to old tools, furniture, etc.
The same reaction occurs in linseed oil and the things coated in it to protect it. If I'm not mistaken the double bonds in the unsaturated fatty acid chains undergo epoxide formation then from there they cross polymerize to form a *fairly* durable coating. It used to be used to protect wood and paintings (In fact if I'm not mistaken it was even used on the Mona Lisa for preservation (at the time) I've played around with it a bit myself and I must say that yeah it's very cool once it dries properly, made a waterproofing solution that I applied to my hat, hiking stick, and a pair of puttees that I wanted to try out. And it worked really well to keep water out
@@neillcoetzer9133 I believe poppyseed oil and walnut oil were also used in oil paints. Different "drying" times and resistance to yellowing.
Not only was nylon developed by DuPont but the project was actually developed involving two offices of DuPont. The one office was in New York the other office was in London. Eventually when the two offices completed their research they decided to call the product nylon. Ny is an abbreviation for New York lon Is an abbreviation for London.
DuPont had a HUGE hand in making Hemp illegal (ALL cannabis types) because it was the ONLY competition to his cursed and damned nylon!!! >> Tom's Ukrainian/American wife Pam
I suppose it's a good thing they didn't involve their Barcelona office. How may women would want to wear BaLoNY on their legs?
Didn't the national socialists develope nylon?
A german company in my town use to make nylon, Bemberg
@@tomfromoz8527 well corporate practices do require having no competition sadly and prefer ruining people lives so that they can help fix it ofc for money

You skipped right by safety film, made by Kodak, using CAB (celluloid acetate butyrate). Mixed with squalene or xylene to make dope, which could be dyed to make thermal resistant plastic or fuel proof paint. CAB mixed with acetone becomes a see-thru plastic known as acrylic.

@@alanmumford8806 Well aren't you the jealous fella? Why's common, beginner level chemistry upset you? Does everyone who knows anything have to make it a video to be valid? Where's your video at showing why you got such a salty attitude?
@@thevalorousdong7675 Jealous? Not at all. Upset by chemistry? Not at all. I have no idea where you got those concepts from. And it seems to me that you are the salty one, on somebody else's behalf too! The guy takes the time and trouble to make an informative and entertaining video covering a small segment of a vast field of knowledge, then gets criticized for what he left out? Where was he supposed to stop? The video was less than 20 minutes, of course there would be stuff that was left out! The comment by jackdeath was entirely pointless and unnecessarily negative. That was my only point. Unless you and jackdeath are the same person, your response is similarly pointless and unnecessarily negative. Have a good day, I hope your mood improves.

Very informative vid thanks! Look forward to checking out more on your channel
Had been wondering about the plastics I've come in contact with over my lifetime , thank you , you've covered them all , from the earliest to the more recent . Believe it or not , I still have some of the various plastics mentioned .
So many stunning demonstrations in this video! Well done man, fascinating! 👍

As an alchemist I constantly work on things I don't understand. I found you learn much faster that way. Autodidactic is the fastest way.

Thank you, that was really interesting
This was an excellent video. I really enjoyed it. I was so interested, that I was surprised when it ended.
No. Because it does not answer at all the question in the title of the video: "Why This SUBSTANCE Was Banned Forever?" What substance and why?
Denture plastic made from fermaldihyde, the pink plastic polymer was the banned substance around 4:38
Great content as always

Very interesting, thank you! As a collector of vintage fountain pens I'm very familiar with celluloid Parkesine, Catalan, etc. Beautiful coloring and effects are possible that can't be done with Bakelite, but yes it is extremely flammable stuff and highly reactive with even very mild solvents. It also has the disadvantage, especially the earlier celluloid formulations, of being quite unstable: off-gassing camphor causes celluloid items to become very brittle and crumble apart. It's a shame because eventually all the antique celluloid items will have crumbled apart to dust.
Fascinating subject, thanks for posting this

In regards to the Teflon pan I've found that no decomposition happens if used on a hotplate, but when used on a gasflame it breaks down the coating. I still have a 13+yr old Teflon pan still in great condition bcoz it's never been used over a flame
Interesting, I guess that's why mine unknowingly also has lasted through the years. Thanks!
I've never seen a Teflon coated pan last t more than a year or so even when careful not to use metal on it or scratchy things to clean it orr overheat it. I only use stainless steel cookware because it lasts forever and there's no chemicals on it. Cast iron as well. The stainless cookware I got for my wife years ago will likely last the rest of our lives but any non-stick pans we've had have had to been thrown away after about a year.
@@dickJohnsonpeter Love my cast iron, I redid one of my older ones and it works about as well as some non-stick pans. Also starting to switch over to more stainless steel myself.
Teflon breaks down over about 350' Celsius. Flames are just too hot for Teflon pans
I loved watching the formation of those polymer pillars under the water to make that whitish pink polymer in those cylindrical beakers. (BTW is it possible to chemically reproduce the slime hagfish produce naturally?)
Thank you for explaining how to properly cook with Teflon. Maybe the sensations in my chest are actually something to do with not understanding that some sort of controlling coolant like thin layer of oil or water is wise and necessary
I try to stay away from teflon now. I only either iron or aluminium now. Sure you have to season it, but I have the peace of mind.
@@johntrevy1 some people think aluminum is linked to alzheimers
@@mikekokomomike This was disproven in the early 1990's. (Biologist who lived through that era.)
@@johntrevy1 I believe that we have a lot of medical implants (like in joints) that incorporate Teflon and have thereby undergone lots of testing to make sure it's not going to degrade, thereby poisoning us. As he mentions in the video though, we can't digest it, so apparently harmless of consumed anyhow. To me that rules out both ingested and blood poisoning routes, making it quite safe. (not to say that it couldn't perhaps over time, or if an entire pan's coating worth, the consumption couldn't somehow become stuck/accumulate and cause an inflammatory reaction that speaks out of control; same for inhaling it if burned or as dust, but that pretty much goes for _anything_ that's "safe" if you burn or instill it as a dust! lol)
@@KB4QAA the only thing I remember about the controversy was there was an increased amount of aluminum found in the brains of Alzheimer patients, and it wasn't known if this was from excess exposure or some metabolic mechanism of the the disease that caused the accumulation. I quit using anti perspirant containing aluminum, avoid aluminum in food and supplements. Maybe nothing to it. Easy enough to do.
That was very interesting, great job
The real problem with Teflon isn't potentially ingesting it, but rather the really bad chemicals used in manufacturing that are often released into the environment
There is more than that. My wife has a parrot. We own NO teflon. That shit is released into the air when it gets hot and it will kill birds. (and it's not good for us either)
The teflon scandal was teflon released in the air during production, teflon was the by product "bad chemicals" you speak of. Causing harm from ingestion after making its way to water supplies, then animals, then humans who ate those animals.
@@YusuphYT Like i said, At high temps Teflon WILL go air born and kill pets. You HAVE to add something to the pan to try and keep the Teflon temp down and even then you can't do anything to the sides. Either way you end up with harmful vapors being put into the air.
One time I had to dispose of a small amount of HCFC refrigerant, and I figured it would be better for the ozone layer to thermally decompose it rather than vent it directly to atmosphere. The flame was a beautiful green color, but the HF and HCl gas byproducts were exceedingly unpleasant when standing downwind of the torch. I'd imagine Teflon breaks down into similar compounds as well, if overheated.
It's a problem both in manufacture - improper disposal of waste - and to the human condition . At present we have no idea the issues from long term exposure to it . 100 % , of Americans have Teflon in their blood . My family got a nonstick fry pan when they came available where we live . It took just over 5 years of regular use , for the polymer coating to fall off . It still worked so was kept going & to my knowledge , no more nonstick apliences have been purchased for use within the home .
Thoisoi! Glad you’re still around!!
Before I knew that the English language videos your dubbed, I drove myself crazy trying to obtain lip sync. It wasn't until I gave up that I learned (from my son, thanks to him) that the lips were never going to match the audio because you weren't speaking English in the original videos! Love your channels.
@Chetar Ruby From what I believe, he doing the dubbed also, so it all him?
this is generally why dubbed videos have the original audio in the background as well
DONT BOTHER WATCHING FOR BANNED SUBSTANCE IT WAS CLICK-BAIT.
@@dh2032 it is all him, oretty sure
@Chetar Ruby his accent is quite heavy and he mispronounces a lot of words, so I think he's reading his dubbing, and it probably takes him a few takes to get as much as possible right. Doing video retakes would be painful and also boring to see in his case. He isn't a fluent speaker or a language specialist and I think dubbing works much better for him
Took me some time I understand you without concentrating hard, but I got used to it and I must say this channel is a GEM.
Boiled Linseed oil, Balsam and other plant resins cross-link to form tough, relatively inert materials. What disqualifies them from being plastics is that these materials cannot be readily shaped once polymerization is complete. Like dried paint, there is no shifting them without damage.
There is thermoset plastics and thermoplastic type plastic one ya mix and form then when it sets it resists melting like epoxy the other type you heat up to melt it then form it before it cools back down like pvc
If anyone is curious, his cool robot shirt says "Что ж давайте разбираться" which is "Well let's figure it out!"
Truly excellent video. Where do you buy that sweatshirt you're wearing at 7:51?
Very good. Very interesting. Thanks.
I have a "properly seasoned" cast iron pan that is a better non-stick surface than Teflon, without the health risks.
Yep. Have one I’ve been working on for ten years and it’s nearly impenetrable.
That wonderful black coating is almost pure crystalline carbon, harder than graphite but wonderfully non stick.
If anybody is wondering "properly" seasoned involves a clean pan heat to drive off moisture add neutral oil like canola. Rub as much off with a towel as you can. You can't rub too much off. Stuff it inverted in a preheated 450F oven for 1.5 hr. Allow to cool. Repeat say 5 more times. If it isn't smokin it isn't seasoning. It won't ever be as slippery as ptfe but it's pretty good non stick plastic surface and stands up to soap cleaning just fine.
@@1boobtube in my twenty plus years experience that is what I’ve heard over and over but doesn’t begin to create a seasoned pan. It takes years of repeated cooking and cleaning properly to build a great season and non stick surface. Many many experts on the internet. Few who know the true art of the thing.
@@MichaelClark-uw7ex Well the seasoning did get messed up once, and it took quite a while to get it back to being right. It works great. i love cooking with cast iron, but it does require maintained. It's not as easy as Teflon, but it works better and lasts longer, so long as you maintain it.
This was one of your most interesting videoes.
I would really love to know more about the dry water material!

Super! Thank you very much!
And this is why i never use teflon fir food, only ceramic coating instead of teflon (hoping its not shedding any material)
Teflon is essentially inert. Eating tiny amounts isn't going to do anything bad to you
@@chemistryofquestionablequa6252 teflon itself is practically inert, but teflon breaks down into nasty chemicals (known as PFOS/PFOA/PFAS) above 250°C which you don't want to eat/breathe.
@@millieno That’s why you have to take care when first using a teflon pan. The vapor coming from a new teflon pan is so toxic that it will kill bigger birds like parrots and cockatoo’s
If you put the time and effort into a cast iron pan it’s impenetrable to food stick. Takes a few years in my experience. But you can scorch them, use metal tools, beat them up, and they won’t poison you.
@@fensoxx Oh yeah i love those, have one myself, if you make pancakes it makes for a good workout to ^^
Wow I always assumed Teflon was some kind of alloyed metal it never even occurred to me that it could be a type of plastic. I also never have been told/figured out about it's 250C maximum operating temperature so thanks for the safety tips!

Teflon heat shrink tubing actually requires you to heat it to 625F / 329C in order to shrink it and it creates a tiny amount of hydrogen flouride in the process. Basically you heat it till it turns clear (gel state) and no more than that. Because of that it has to be done under a fume hood or outside.
Very informative and pleasently authentic presentation. I would be interested in the recyclability of common plastics. For example how to regain water out of the pampers-polymer.
We can also thank Dupont and other companies for C8 - Perfluorooctanoic acid (PFOA) which has been found in nearly every single human around the world. Not a good thing.
Always interesting!
