Most foam is made from polyurethane.
They start by making polyurethane. To make it, you mix a polyol with a diisocyanate. There are many polyols. There are two important isocyanates, toluene diisocyanate and methylene diisocyanate. (Two other diisocyanates are used to make urethane paint.) The choice of polyol governs whether the foam is hard or soft, and how soft or hard it is.
Next, you mix in a blowing agent. The first blowing agent was water, which forms CO2 in contact with diisocyanate. They don't like making insulating foam with water, because the foam doesn't insulate as well.

How do you deal with bottom line problem during foam manufacturing?
Ypu raise the top line with your copious quantities of foam.
What is the relation of acetone in a mattress foam?
Acetone is not typically part of the composition of mattress foam. It is a solvent commonly used in industry for various purposes but is not a standard material in foam manufacturing.
Is soundproofing foam the best method of soundproofing?
Soundproofing foam is a good method for sound proofing. There are also several other good methods for soundproofing a home.
What is the best method for using foam to fill holes in a wall?
The best method for using foam to fill holes in a wall is to first clean the area around the hole, then insert the foam nozzle into the hole and slowly fill it with foam. Allow the foam to expand and dry completely before trimming off any excess foam and sanding it smooth for a finished look.
What is the best method for creating an elephant foam recipe?
The best method for creating an elephant foam recipe is to use a combination of soap or detergent, water, and a foam dispenser. Mix the soap or detergent with water in the dispenser and pump to create foam. Adjust the ratio of soap to water for desired consistency.
What manufacturing method was used by Henry ford?
Assembly-line method of production.
What materials should memory foam best be made out of?
Memory foam is based on polyurethane foam but can have a number of additives, depending on the manufacturer. One idea for improved composition of memory foam is to use "green" products such as a soy base to minimize the environmental impact of the manufacturing process.
What are the advantages in viewing manufacturing as a system?
Manufacturing is what it is, regardless what you call it. But as far as words go, and their Definitions, A system is prone to Failures, whereas a Method, is a strict set of operational rules, whereas a Process is a means to a end. So Manufacturing is a Process, not a System, and not a Method, lest you consider the Process, the Method for Manufacturing. And in the End, perhaps it's all three.
What is the density of PVC foam?
The density of PVC foam can vary depending on the specific formulation and manufacturing process. However, it typically ranges from 50 kg/m3 to 100 kg/m3.
What is balasa foam?
Balasa foam is a type of foam material that is often used in packaging, cushioning, and insulation applications. It is known for its lightweight and buoyant properties, making it suitable for various purposes requiring cushioning or protection. Balasa foam is commonly used in the transportation and manufacturing industries.
Is a foam pillow a conductor or an insulator?
This depends on the type of foam. There have been made foam that actually conduct electricity. This is a choice made in the manufacturing of the foam. Most foam in mattresses and the like does not conduct electricity. Moisture however can change the mattresses conductivity drastically.
What is simple afrosimetric method used to estimate the saponins?
The foam test is a simple and quick afrosimetric method used to estimate the presence of saponins in a sample. It involves shaking the sample with water or dilute ethanol and observing the formation of stable foam. The more abundant the saponins, the more intense and stable the foam.
