Making PU (Polyurethane) foam

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:

What are the names of the rwa materials (Chemical) used?

[blackfordoblique]

So the way to make foam is to buy it.
Got it. Thanks. Really great, man!

[vishalkariya]

Which chemical are used? And in which quantities ratio?

[ic]

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

[moosemoose]

Great information, thanks!
Surprised you weren't wearing gloves 😜

[asdfsfasdfasd]

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.

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.

[Martink]

It seems similar to foam used for insulation in home. Is it so?

[Teenagerz]

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

[Salador]

What is the cost like on that box mold?
What do you do with the block? I assume you use the
Whole thing or do you sculpt it? Trying to figure out this cost wise or whatever you can tell us if u see this, i know it's been about five years

[shafqatazeem]

Hi dear
please mention the names of chemicals
And quantity as per coverage area..

thanks for the hint to the band "Loco Lobo" - 02. Jonny pass auf (ID 290) (06:23) so funny : )

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 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.

Maybe you can make the bumper more rigid (if needed?) by filling parts of the back with pu foam spray? 🤷🏼

[k.w]

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.

1:27 the forbidden pancakes are flipped 😂

[sushilmanandhar]

Can you tell me the names of the products you used? What is the density? What you did ? Please

[chilllee]

Can this now be carved, sanded, painted then finished? Does it hold small details?! Thx 😎

[lorrainedixon]

I wonder what the results of that with concrete mix?
