Some, maybe most, polyurethane is a liquid at room temperature. The solid forms of polyurethane can vary from very hard, like casters and hammer heads, to very soft, almost jelly like, or like the softest parts of the human body (rather creepy). The foamed forms of polyurethane can be flexible foam in chair cushions and mattresses, or rigid foam as in spray in rigid wall or ceiling insulation. Depending on the formulation, the foam may be mostly intact air tight cells, or may be open mesh-like structure The density may vary from a few pounds per cubic foot to the density of solid polyurethane. If foam polyurethane is poured into a sealed mold, you can end up with solid walls, and a foam core. Rather amazing material
The hardness rating is called "durometer" rating just a note about the technical verbage used with this product, I have used two part polymer urethane in various automotive modifications (suspension components, body mounts, motor mounts) etc.
The raw material primarily used in the production of polyurethane is diisocyanate. Specifically, there are two main types of diisocyanates commonly used: toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI). These diisocyanates react with polyols to form polyurethane polymers, which can be molded into various shapes or used as coatings, adhesives, or flexible or rigid foams depending on the formulation and processing conditions. 🙌
@@insidefactories The punctuation and pronunciation is pretty much what current AI models would do... Does that mean your narrator learned from a machine? xD But than on the other side most Scottish people sound like children to me because of the accent.
