We arean active member of multiple industry associations, such asISOPA, PU Europe, Europur and the IVPU.5

Monomeric MDIMonomeric MDI (MMDI) refers to 4,4’- and 2,4’-isomers ofmethylene diphenyl diisocyanate. BASF offers two standardmonomeric MDI grades: pure 4,4’-MDI and a blend of 4,4’-MDIand 2,4’-MDI. Besides the standard MMDIs, various MMDItypes with different stabilization and reactivity are available.Although pure 4,4’-MDI is a crystalline solid at room temperature,it is commercially available as a liquid but with a limited shelflife. Monomeric MDIs are either used as pure isocyanate, inmixtures with polymeric MDI (PMDI) or in prepolymers forflexible foams, CASE applications, shoe soles or thermoplasticpolyurethanes.Monomeric Methylene Diphenyl Diisocyanates (MMDI)ProductNCO content[%]Lupranat ME33,5Lupranat MILupranat MIPViscosity[mPa*s]ViscosityTemperature [ C]Description542Pure monomeric 4,4’-MDI.

These products contain a portion ofMMDI that is reacted to give a tri-functional uretonimine specieswithin the remaining difunctional MMDI.

Polymeric MDIPolymeric methylene diphenyl diisocyanate (PMDI) is a brownmixture of monomeric (2-ring) and polyaromatic (3-ring andhigher species) methylene diphenyl diisocyanates, which is liquidat room temperature. A higher PMDI viscosity indicates a lowercontent of monomeric and a higher content of polyaromaticcomponents; that is, as PMDI viscosity increases, so doesisocyanate functionality. BASF offers a range of PMDIs withdifferent functionality and reactivity. PMDI is mainly used forthe production of rigid foam. PMDI grades are also used as abinder in the wood-working industry. In combination with MMDIgrades, polymeric MDI is also used to produce various types offlexible foam and for CASE applications.Polymeric Methylene Diphenyl Diisocyanates (PMDI)ProductNCO content[%]Viscosity[mPa*s]ViscosityTemperature [ C]DescriptionLupranat M 10 R31,511025Polymeric MDI with lower functionality and higher reactivity.Lupranat M 20 R31,522025Polymeric MDI with average functionality and reduced reactivity.Lupranat M 20 S31,521025Polymeric MDI with average functionality and reactivity.
