Toluene Diisocyanate (TDI) is a fundamental chemical intermediate with widespread importance across numerous industrial sectors. As a key component in the production of polyurethanes, its properties and applications are central to modern manufacturing. NINGBO INNO PHARMCHEM CO.,LTD. specializes in supplying high-quality TDI, ensuring that industries have access to a reliable source of this essential compound. This article highlights the significance of TDI as a chemical intermediate and its role in driving industrial innovation.

The chemical identity of Toluene Diisocyanate is well-defined by its CAS number 26471-62-5 and molecular formula C9H6N2O2. It is an aromatic diisocyanate, meaning it possesses two isocyanate (-N=C=O) functional groups attached to a toluene ring. This bifunctional nature is what allows it to react with compounds containing active hydrogen atoms, most notably polyols, to form polymers. The typical industrial grade of TDI is a mixture of isomers, predominantly 2,4-TDI and 2,6-TDI, with the 80/20 ratio being the most common. The purity of TDI, typically above 99.5%, is critical for consistent reaction outcomes in downstream applications. Factors like isomeric composition, acidity, and color are carefully controlled to meet the diverse needs of manufacturers.

The primary application driving the demand for Toluene Diisocyanate is its use in the synthesis of polyurethanes. However, its utility as a chemical intermediate extends beyond just flexible foams. It is also integral to the production of polyurethane coatings, adhesives, sealants, and elastomers (CASE applications). These materials find their way into countless products, from automotive parts and construction materials to consumer goods and industrial equipment. The ability of TDI to create polymers with a wide range of mechanical properties—from soft and flexible to rigid and tough—makes it an exceptionally versatile intermediate.
