How Foam Made In a Factory? PU Foam, HR foam & Memory Foam कैसे बनता है?

Polyurethane foam is used primarily for bedding and furniture stuffing.
Isocyanates and Polyols
We have two foundational chemicals involved in the foaming of PU. Isocyanates and Polyols contain multiple hydroxyl.
In the foaming, the two most common isocyanates are TDI (for flexible and semi-rigid foaming) and MDI (for rigid foaming).
TDI + polyol has made polyurethane polymer, which now can be expanded to make foam. To do that, we add water. Isocyanate is highly reactive, and produces two things with water: urea linkages/urethane, and carbon dioxide (CO2) gas.
Blowing the Foam
The CO2 is considered primary blowing agent. As a gas, it blows little air pockets into the PU to form the foam. Just like blowing soap bubbles though, there is a point when the liquid casing cannot withstand the pressure of the air inside and bursts.
To successfully make material foam, the polyurethane must gel into shape once air has been blown to it. It’s harder than it sounds, and it’s also why foam technicians can make or break your factory production. The art of foam-making revolves around this sensitive balance between expansion, or blowing, and gelling.
Once they’re formed inside the polyurethane, we’re going to call the air bubbles cells. If the foam expands and gels before any air bubbles burst, you get closed-cell foams, which are semi-rigid (not truly rigid like foam made of MDI) since the material doesn’t bend as easily. To go back to our ladder metaphor, closed-cell foams are like wood ladders, whereas open-cell foams are like rope ladders. If some or all cell walls are allowed to rupture before gellation, you get a much more flexible material that bends, twists, and even breaks easier.
what is polyurethane foam? Basically: TDI, polyol, water, polymer, open versus closed-cell.
Additives.
see PU foaming additives by function. One of the most important additives is the catalyst, which can affect the basic reactions in several ways. It can speed the expansion, speed the gelling, cool the reaction (so you have less of a fire hazard on your hands), etc. There are also curing agents, which include chain-extenders and cross-linking agents. Chain-extenders, like their name suggests, extend polymer chains, which increases material flexibility. Cross-linking agents promote and strengthen cross-linkages, increasing structural integrity for more rigid foams.
Think of surfactants like emulsifiers. Oil and water on their own do not mix, but once you add some dish soap, they can be emulsified into a uniform mixture. Surfactants work like the soap. A more uniform mixture means a smoother reaction, and you get more even cell sizes, steadier reaction speeds, and finer control between gellation and foam collapse.
(The reason they’re called surfactants is because they reduce the surface, or interface tensions between two compounds. As in, the oil doesn’t just sit neatly on top of the water surfactants blend that interfacing surface between them.)
PU Foaming Chemistry oil
Remember that CO2 gas from the reaction with water acts as a blowing agent? other blowing agents may also be used or added. The main inconvenience of water blowing is the high temperature of the reaction, making PU foaming a fire hazard. Physical blowing agents (additives that physically encourage the expansion of cells instead of that initial CO2, which is chemically blown) reduce that fire hazard.
A similar additives is fillers. They come as particles or fibers. Particulate fillers can reduce flammability and add weight to foam (good for cushioning foams). Fibrous fillers reinforce cell structure. All fillers function to 1) add physical properties like tensile or compressive strength to foam, and 2) save on costs by reducing the amount of liquid chemicals used per batch.
The main ingredients are.
Isocyanate: TDI
Polyol: polyol
Blowing Agents: water, methylene-chloride (MC)
Catalysts: amine, tin
Surfactant: silicone
Now we understand what each element does during the foaming process. TDI + polyol begins the creation of polyurethane. A mixing head first injects small amounts of air into the liquid mix to kickstart the foaming process. TDI + water chemically produces the CO2 gas that blows the liquid into foam. In addition, we add MC so that less water is used in the initial reaction and the overall reaction temperature is lower, all while cell expansion is retained.
Meanwhile, the amine additive is doing multi-purpose catalysis (speeding the reaction) and tin provides a stable gelling catalyst, increasing foam structural elasticity. Silicone smooths and steadies the entire blowing process, maintaining cell structure evenness until gellation occurs.
Nice to see youth of India making their presence in the market.
This is reality of Indian manufacturer...no safety with Gloves...safety shoes ...gujju owner at there best
boss don't care if they don't have workers plenty waiting to take a job
We should appreciate the guys who has worked so hard to bring this knowledge and such a simple and explanatory way. these videos are for learning and not to finding issues in owners and employees. They have shown how simple is the foam making process wow!! Amazing !! the the chemicals used does not seems to create any safety or security issue than what is the point using cloves and glasses. will go out in park with safety glasses.
Catalyst increases the speed of reaction of different chemicals mixed.

nice that you tell how its made, one problem, nobody is wearing any protection against gasses and chemicals. Be a better boss and take care of the protection off your workers and yourself !!
I dont think you understand what i am saying ? you are doing it very bad for your workers. take better care off them !!

Hello sir How much capital will be required to set up foam manufacturing factory?
AROUND 4 MILLION DOLLARS
Bro,Would you kindly visit the bamboo ply factory as you are doing now and show how it's made🙏
👍👍👍
Very nice
🙏💐
We need only POL+ISO, and also Heat at its all edges of cover. No other chemical required for PU foam. Yes, you can apply Acmose at the edges as releasing agent.
What are the materials bro??
@@sifeddinezeroual4860 as discussed above we only need Polyol and Isocynate at specific ratio. While pouring mould temperature should be on 45-55 degree.
What is POL ?
@@imrankhanafi5423 Polyol and Isocynide

Os produtos são forte o cheiro da reação química, se deixar os blocos juntos e perigoso pegar fogo devido a caloria da reação química, tem que deixar os blocos descansar sem encostar um ao outro, há caso que galpão pegou fogo
Kya aap silicone sponge banate ho ?
Please reply
Foam formed quickly. I thought its a slow process.
The building's safety cannot be assured. No safety boots, gloves, or masks are worn. There are no warning signs for safety, such as No Smoking. There are no obvious chemical warning indicators. Poor storage of chemicals. Chemicals must be kept in a well-ventilated chemical storage area. No designated power control room makes the power supply extremely risky. Numerous unorganised, unsecured items in the area could hurt the workers.
