Methylene Diphenyl Diisocyanate (MDI) CAS:101-68-8 Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock. There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MDI contains monomeric MDI and products with higher […]

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.
Hexamethylenediamine (HMD) is obtained from hydrogenation of the adiponitrile.
HMD and adipic acid are the starting materials for nylon 6,6 used widely in textiles and plastics. HMD reduce yellowing in PU resin. HMD can react with the phosgene and produce the HexamethylenDiIsocyanate (HDI).
The main uses are epoxy curing agents, petroleum, adhesives, inks, scale and corrosion inhibitors, water treatment chemicals and disinfectants.
HMD is moderately toxic. It can cause serious burns and severe irritation.
This product can be founded as various grade : HMD 100% – HMD 90% – HMD 80% – HMD 70%
