Diphenylmethane diisocyanate (MDI) is a member of the diisocyanate family associated with polyurethane chemistry. The term polyurethane applies to a large number of polymers formed through the polyaddition of polyfunctional isocyanates and isocyanate-reactive polyfunctional compounds.
What is MDI in adhesives?
Methylene diphenyl diisocyanate, or MDI, is a very versatile molecule that delivers different performance properties for a variety of applications. Primary end uses for MDI include: Foam insulation for appliances and construction. Binders for composite wood products. Adhesives/sealants for flooring laminates.Methylene diphenyl diisocyanateMethylene diphenyl diisocyanateMethylene diphenyl diisocyanate (MDI) is an aromatic diisocyanate. The 4,4′ isomer is most widely used, and is also known as 4,4′-diphenylmethane diisocyanate. This isomer is also known as Pure MDI. MDI reacts with polyols in the manufacture of polyurethane.https://en.wikipedia.org › Methylene_diphenyl_diisocyanateMethylene diphenyl diisocyanate - Wikipedia, or MDI, is a very versatile molecule that delivers different performance properties for a variety of applications.

Is MDI a hazardous material?
A material is considered a hazardous waste if (1) it is a listed hazardous waste published by EPA in 40 CFR Part 261, Subpart D or (2) exhibits at least one of the four characteristics defined in 40 CFR 261, Subpart C.
Is polymeric MDI flammable?
MDI stands for methylene diphenyl diisocyanate; it is available in pure forms such as 4,4'-MDI, or as a mixture of isomers and different molecular weight oligomers in polymeric MDI or PMDI. MDI and TDI do not catch fire or burn easily, but they may be involved in a fire which is spread by other materials.
Is MDI carcinogenic?
Chronic (long-term) inhalation exposure to MDI has been shown to cause asthma, dyspnea, and other respiratory impairments in workers. EPA has classified MDI as a Group D, not classifiable as to human carcinogenicity.
Is MDI corrosive?
MDI is not generally corrosive towards metals or other materials at room temperature, but the presence of a small amount of acidity in PMDI can produce some corrosion with copper alloys and aluminum.

Is MDI toxic?
MDI has low acute toxicity via the oral and dermal routes, but is considered toxic via the inhalation route in animals (Collins, 2002; ECB, 2005).
