What is the manufacturing method of foam?
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.
