Polyurethane foams NEW

Uses:

Polyurethane foam (CAS NO.9009-54-5) are used in aviation, railways, architecture, sports, etc. It can be used for precast polyurethane board. It also can be used in the manufacture of plastic products, wear-resisting synthesis rubber products, synthetic fiber, hard and soft foam plastics, adhesives and coating.

Production:

Polyurethane foams (CAS NO.9009-54-5) are manufactured from a diisocyanate, such as toluene diisocyanate (TDI), and a low-molecular-weight polyether such as poly (propylene glycol).
In the process, a small amount of water is added to convert some isocyanate functionalities into carbon dioxide and amines. The degree of foaming can be controlled by the amount of water added.
 One way of obtaining the more useful cross-linked polyurethanes is by using a trifunctional reagent. Thus either the toluene diisocyanate can react with a triol or the propylene oxide can be polymerized in the presence of a triol.
