MDI (METHYLENE DI-P-PHENYLENE ISOCYANATE) Chemical compatibility with O-rings, rubbers, & plastics

Methylene diphenyl diisocyanate, commonly called MDI and sometimes referred to as methylene di-p-phenylene isocyanate, is an aromatic isocyanate compound with the chemical formula C15H10N2O2 widely used in the manufacture of polyurethane foams, elastomers, coatings, adhesives, and sealants. It is also used as a binder in engineered wood products such as particleboard and composite panels. Because MDI is a reactive chemical that can irritate the respiratory system, skin, and eyes, exposure must be carefully controlled. In equipment containing MDI, O-rings, rubber seals, gaskets, and plastic components should be evaluated for chemical compatibility to prevent degradation. Proper handling, storage, ventilation, and protective equipment are essential for safe industrial use.
