Methylene Diphenyl Diisocyanate (MDI) Market Synopsis. As of 2019, the largest producer of the compound was Wanhua Chemical Group. MDI stands for methylene diphenyl diisocyanate; it is available in pure forms such as 4,4’-MDI, or as a mixture of isomers and different molecular weight oligomers in polymeric MDI or PMDI. Airborne MDI concentrations during manufacturing processes are influenced by whether the material is heated or sprayed, how the diisocyanate is reacted or cured, whether the process is conducted in an open or closed system, and the types of sampling methods used (Boothet al., 2009).
