MDI(METHYLENE DIPHENYL DIISOCYNATE)

Product price	Consultation required
Product information	Aromatic diisocyanates chemicals largely classified into MDI monomers and Polymeric MDIs. MDI monomers are composed of three isomers: 2,2′-MDI, 2,4′-MDI and 4,4′-MDI, among which 4,4`-isomer is called pure MDI or Monomeric MDI, and Polymeric MDI is a combination of monomeric MDI and higher molecular weight polynuclear methylene diphenyl diisocyanate.

Product Description

Polymeric MDIUsed in various ways including Polymeric MDI Rigid Foam, Semi-hard Foam, CASE fields etc. Because it is categorized into various grades according to the viscosity, it can be selected according to the use.
Monomeric MDIMonomeric MDI has the form of white solid at room temperature, and it has transparency like water when it exists as liquid. Especially, it has strong discoloration resistance and excellent anti-discoloration stability against high temperature and ultraviolet rays.
