- Short video on how polyurethane foam is made. It is bought in liquid form in two chemical components, that once mixed it reacts and the foam is created. There are rigid and flexible foams as well as different densities, check which one you are buying!
I am surprised and grateful for so many visits and questions, I am terribly sorry I cannot reply to all of you.
I am not an expert on foams or chemist. I am an industrial designer, the material I used in this demonstration is this one:

So the way to make foam is to buy it.
Got it. Thanks. Really great, man!
🤣
Yer comes premixed in a can too, and it would be great to make a box shape block of foam.
Don’t forget to lick the bowl.
😜😜😂😂😂😂
Watching the dough rise 🥰
Great information, thanks!
Surprised you weren't wearing gloves 😜
Gloves cost money just don't get it on your hands. Or wear gloves. What type of gloves stop those chemicals? Probably not the ones you'll be wearing. Better to just stay clean. It's professional.
thanks for the hint to the band "Loco Lobo" - 02. Jonny pass auf (ID 290) (06:23) so funny : )
Maybe you can make the bumper more rigid (if needed?) by filling parts of the back with pu foam spray? 🤷🏼
Thanks Doc ,you até!chemist
You need to read up on isocynate exposure
I searched up foam asmr and this showed up
Oh its very enteresting
Good, I want to use this products but I need table of the all ratio dosage, pressure and time mixing from 1 kg to 2000 kg with acceleration and curing agent and sample, can your provide me this information
Good day friend, I am dedicated to the manufacture of polyurethane foams of different densities and characteristics, I can gladly provide advice, consultation and information on materials, formulations and procedures
Hi dear
please mention the names of chemicals
And quantity as per coverage area..
Polyurethane foam, component A and component B, expand x4 the volume

Look at you go. Atta boy.
Can this spray foam be used on car's noise cancelation? How's the sound proofing ability 😮😊 just curious about the possibility as it looks pretty light.
It seems similar to foam used for insulation in home. Is it so?
Which chemical are used? And in which quantities ratio?
It is a product you buy in two parts like epoxy, u don't really make it yourself it's formulated and you need to know which properties you need from it so you choose accordingly these are very engineered products that cannot really be modified or created at home. In fact you shouldn't do this at home, you would need a shop space. It's toxic AF in some ways, at least for the initial cure but in many cases tiny residual toxicity for years or the lifetime of the product. Look it up.

very nice 👌👌👏👏👏
The forbidden loaf
the unfortunate downside to foams like this and the handful of others that are available to the consumer in consumer quanties that are safe to ship, etc. that they do not contain the best chemistry like that which would be used in commonly available slab or bunstock foams for cushioning (furniture) or mattresses/bedding. The blowing agents, different polyol and polyol-prepolymer mixes, the catalyst choice, and the 2ndary set of componnets like flame retardants and even surfactants are all highly engineered...... but even more critically: These mixtures and even the chemicals used to make them are HEAVILY patented and protected by trade secrets and aggressively protected by the very companies who are ultimately supplying the retail companies with their bulk mixtures (or even doing the custom formulating for them as a white label supplier). I'm talking Huntsman, BASF, Solvay, etc. Honestly, I would be weary of using this type of foam for constant physical interaction due to the catalyst alone.
1:27 the forbidden pancakes are flipped 😂
What are the names of the rwa materials (Chemical) used?
SOMEONE?
Polyol, TDI , amine , stannous, silicon, water, methylene chloride,
Main 2 is --- polyol and TDI ( toulene diisocyanate

Super bravo
👏👏👏
Can this now be carved,sanded,painted then finished? Does it hold small details?! Thx 😎
I wonder what the results of that with concrete mix?
Can you tell me the names of the products you used? What is the density? What you did ? Please
Great video. How much roughly would this piece cost in materials?.
Well he roughly used around 200 grams of material, current market price(europe),judging that you are not buying in bulk would be 0.50-0.60 Euros or something.
@@cankural2501 Do you know any supplier that will sell this polyurethane at 3 EUR per kg ? Thanks a lot.
@@danielcrall9507 polyol and isocyante required vary vastly for each usage, the company Im working for is based in turkey and we are distributor for BASF in flexible foam segment also we do supply various polyols mainly(slabstock and case application) and also tdi(t80/20,t65) and mdi(polymeric,monomeric). As you may expect price vary based on the location you want us to send the material to and quantity and specs.
@@cankural2501 please give me your contact information. It is really important. Thank you.
Is this what is used in beds, what chemicals are used to make bed foam. Please assist if possible
Bravo
Put a plastic liner or similar application.
I'm building a racing track. One of the obstacle i'd like to use this foam. What is the ratio of component 1 and component 2? And in case I get it wrong, what is component 1 and component 2
What the name of chemical
Might you know the maximum temp this mixture becomes and for approximately h ow long - when it sets? I have an app where I can see using this to fill voids (to help preventing rattling) in an interior car plastic panel. My concern is that this heat could distort the original shape of the interior panel. Do you know of any such similar products that have a lower cure temp.
I don't think it gets too hot when it reacts. Foam will hold moisture though. That makes cars rust from the inside out.
@@elmeradams8781 i ended up using liquid polyester resin, which i am more familiar using. it did get hot to the touch, easily over 100, probably as i used more catalyst than i should have. but thankfully this heat did not distort the original plastic part i was filling voids with.
Hi Greg, this particular mix does get hot, hot enough to not be able to touch it, but most plastics melting temperature is above 180 celsius, therefore, I think it won't deform the interior panel. But to be sure, there are brands making foams for that specific purpose, I know of "GREAT STUFF", there may be others, better go the safe way.
@@vgmdesign Thanks tons. I never got an answer soon enough for my project. i ended up using liquid polyester resin (as in surfboards, and filling it with that. yes it also got warm or hot when catalyzed. so i only poured in many smaller layers. as well to keep any leakage to a minimum. i will check out your suggestion now, should it ever come in handy in the future.

If you try to cut this material with a hot wire, will it burst into flames?
Hot wire cutting is normally used with polystyrene foam. I have never tried with PU foam, but I would not do it, this foam is a "thermoset" plastic, which means that does not melt and you cannot recycle it. The most probable thing is that it will burn producing nasty fumes... so, better not do it!
Could you recommend one that's more flexible/rubbery when it's formed? I haven't been able to find one. All I have found are the same as the one shown in the video, rigid and hard.
Look for the Smooth On products. Not sure how soft you want it but you can use flex foam 3 to make squishy toys. They have other densities

Can I ask a question, please? Is there a material that does not remove this foam? Thank you. Please reply
Interesting, normally I get asked what material can be used to remove it, as this type of foam attaches strongly, specially to fabrics. But a material that does not remove it, I think the list may be long, it depends what you are trying to do. Sorry for not being more precise.

Besides the plastic film that you added to your wooden box mold, did you use any release agent to coat the plastic prior to pouring?
I like your idea.
I am experimenting now with laser cut foam patterns, in which I will stack all these same cutouts to create a decorative column. This column will approximately 4 foot long. I can't quite figure out how to keep the mold shape's structure. What also comes to my mind is that since the mold will be made from Styrofoam itself, I am trying to figure out how to keep the mold from blowing due to the pressure created from the expanding Styrofoam. not getting stuck to my Styrofoam mold, and not have a difficult time removing the finished column piece from the mold itself.
Thank your for the video. You given me a few good ideas to experiment with soon.
Hello Manuel, no, just the plastic. Just try to avoid any folding of the plastic, because the foam will get trapped in it and it is a bit of a pain later on.

Hello.
I am from Algeria, my country is located in North Africa. I watched your channel and liked its content. I am very interested in making sponge (polyurethane foam) by hand. Because I do not have great financial capabilities.
Please help me. I need to know the amounts of ingredients in kilograms according to known densities, and the dimensions of the basin into which the liquid substance is poured.

What is a components?
Is this foam can float on the water? i mean does not absorb when it is contacted with water?
Polyurethane foam
it will absorb water over time.
Heat generated by the chemical reaction...is it high enough to damage a thin plastic surface???
aslam ali Hi im an Chemical Engineer and i work in Foam Production, it depends on the Denisity of the Foam, foam has a exotherm of 150-165 degree Celsius, but if the Reaction is bad it also can happend that the foam can ignite by itself, if the temperature goes over 165 degree Celsius you have to be carefull.
@@fatonics thanks for replying...
@@fatonics Hi I am working on pu rigid foam for cooler box purposes. I have questions and need help. What type of plastic that is suitable for the mold covering? I only use plastic tape on my wooden mold and silicone oil as covering, but I always make the products cracked on the edge, and on the bottom, it always has Unreacted-Isocyanate like pattern (a bit dark brownish) while on top of the foam is always smooth and bright yellow.
Thank you very much.

How can I used this process to make A Refrigerator insulation?

this is flexible foam, for refrigerator insulation you need to use different substances.(form of Mdi and probably a reactive polyol) It is called Rigid Foam for insulation.
