WebThermoplastic polyurethane (TPU) is a melt-processable thermoplastic elastomer with high durability and flexibility. It has the characteristics of both plastic and rubber and thus … WebPolyurethane foams are produced by reacting polyols and diisocyanates, both products often derived from crude oil. The main diisocynate used in the production of flexible polyurethane foam is TDI (Toluene diisocyanate). Some foams, notably so-called visco-elastic or memory foams, can also be made with MDI (Methylene diphenyl diisocyanate). …
