Toluene Diisocyanate (TDI) CAS:584-84-9 Toluene Diisocyanate  is produced by a 3 step reaction. The first step is the nitration of toluene to obtain dinitrotoluene. Second step is the catalytic hydrogenation of Dinitrotoluene into toluene diamine TDA. Finally, the TDA react with phosgene to produce the TDI. TDI is commonly sold under 3 different ratio isomeric […]

Hexamethylenediamine ( HMD ) (CAS : 124-09-04) Hexamethylenediamine (HMD) also named Hexane-1,6-diamine; 1,6-Hexanediamine or 1,6-Diaminohexane is a chemical compound with two amines functions. Production Hexamethylenediamine (HMD) is obtained from hydrogenation of the adiponitrile. Use HMD and adipic acid are the starting materials for nylon 6,6 used widely in textiles and plastics. HMD reduce yellowing in PU resin. […]
