CEH: Diisocyanates & Polyisocyanates

Dec 2021. Diisocyanates and polyisocyanates are reactive intermediates characterized by terminal isocyanate groups, which typically are reacted with the hydroxyl groups of polyol coreactants to form polyurethanes. The most widely used diisocyanates and polyisocyanates are aromatic in their composition. A product mixture of polymethylenepolyphenylene isocyanate (polymeric MDI) and p,p′-methylene diphenyl diisocyanate (MDI) is derived from aniline (via benzene). Toluene diisocyanate (TDI) is derived from toluene. The global MDI and TDI markets are very large-volume and provide important raw materials for the manufacture of polyurethane products; however, the marketplace is very concentrated, and there is significant worldwide trade in both MDI and TDI. TDI is consumed primarily in flexible polyurethane foams used in cushioning products such as mattresses, furniture, and automotive seats. MDI consumption is mainly for rigid polyurethane foam insulation markets, but it is also used in a variety of nonfoam applications, such as coatings, elastomers, and adhesives for oriented strandboard (OSB) wood composites for construction markets.
