Toluene-2,4-diisocyanate Market Summary
Introduction
The toluene-2,4-diisocyanate market centers on the production and application of a specific isomer of toluene diisocyanate (TDI), representing one of the most commercially important variants in the broader TDI family. Toluene diisocyanate is an organic compound with the formula CH3C6H3(NCO)2, where 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7) are the two commercially significant isomers. The 2,4-isomer dominates commercial applications and is produced both in pure state and as part of mixed formulations. TDI is commonly marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively, with the 2,4-isomer providing superior reactivity characteristics essential for polyurethane production. This chemical serves as a fundamental building block for flexible polyurethane foams, elastomers, coatings, and specialized chemical products. The compound's excellent reactivity profile makes it particularly valuable in applications requiring controlled curing characteristics and superior mechanical properties. Global production capacity is concentrated in Asia Pacific, Europe, and North America, with Asia Pacific, especially China, emerging as the dominant production region due to integrated supply chains, cost advantages, and rapidly growing downstream demand from construction, automotive, and consumer goods sectors.
