Application

 

"Polymeric MDI" (PMDI) is a technical grade MDI which contains 30 to 80 % w/w 4,4'-methylene diphenyl isocyanate; the rest consists of MDI oligomers and MDI homologues.

4,4'-Methylene diphenyl isocyanate is produced in two grades of purity (Schauerte 1983): * pure monomeric 4,4'-methylene diphenyl isocyanate (MDI) (CAS number 101-68-8, EC number 615-005-00-9), at temperatures up to 38 °C a whitish-yellow solid which is used in the industrial production of special plastics, varnish and glue components, moulding elastomers and "MDI prepolymers" (reaction products with polyester or polyether polyalcohols containing an excess of MDI) and which accounts for about 10 % to 15 % of all MDI used, and* technical grade, so-called "polymeric MDI" (PMDI) (CAS number 9016-87-9, EC number 615-005-01-6), dark brown liquids at room temperature which contain between 30 % and 80 % MDI together with higher molecular weight MDI homologues and which are used in numerous industrial plants and workshops, mostly for manufacture of various polyurethane mouldings and products by addition polymerization with polyester or polyether polyalcohols at room temperature. Special applications include core sand binding, chip board production,reinforcement of rock formations in mines.

The production processes for monomeric MDI and PMDI yield products contaminated with the relatively volatile substance, phenylisocyanate. These days, however, the level of phenylisocyanate is generally well below 0.005 % w/w and so is irrelevant for the assessment of the effects of these substances on occupational health.
The spontaneous chemical reaction of the various kinds of MDI with primary or secondary amines or substances with -COOH, -OH or-SH groups is exothermic and complete within seconds or minutes. In humid air, MDI reacts with water vapour and releases CO2 slowly to form a solid surface layer of polyurea.
