The chapter starts a global market overview of methylene diphenyl diisocyanate (MDI) and TDI, followed by the key technical innovations in the MDI process technology that covers condensation, phosgenation, and separation sections, than those in the TDI process technology related to hydrogenation and phosgenation sections. Considering lots of hazardous feedstock are handled in the MDI and TDI processes, isocyanate producers have been taking safety as their first priority, meanwhile reducing the carbon footprint and environmental impact for sustainable growth's sake, thus safety management is important. At last, the chapter introduces Wanhua's safety management system, which covers the whole product life cycle from laboratory research to plant demolition. And how this system was applied in MDI and TDI process was illustrated too. References Founder Securities ( 2020 ). Securities Research Report of Chemical Industry . Wanua Marketing Department .
