Products Description of Polyurethane CAS#9009-54-5
Polyurethanes are prepared using a variety of isocyanates, including tolylene diisocyanate (TDI), hexamethylene diisocyanate (HDI), and dicyclohexylmethane diisocyanate (HMDI). Most of these isocyanates are low-viscosity liquids at room temperature, while 4,4′-diphenylmethane diisocyanate (MDI) exists as a crystalline solid.
Compared with aliphatic isocyanates, aromatic isocyanates exhibit higher reactivity and are widely used in the production of polyurethane foams, coatings, and elastomers. In addition, the cyclic structures of aromatic and alicyclic isocyanates enhance the molecular stiffness of polyurethane materials, contributing to improved mechanical properties.

Product Application of Polyurethane CAS#9009-54-5
Polyurethane is used in a wide range of applications, including prosthetic devices such as internal bone splints.
Polyurethane resins and foams are important industrial polymers that can be manufactured as rigid, semi-rigid, or flexible foams, as well as resin materials, providing excellent versatility across numerous commercial applications. They are widely used in furniture, bedding, automotive sealing materials, adhesives, carpets, packaging materials, coatings, and many other products.
Polyurethane is highly valued for its excellent resistance to oils, light, and solvents, as well as its outstanding strength and flexibility. These polymers are produced through polyaddition reactions between diisocyanates and polyhydroxyl compounds, such as polyols.
