Overview of Methylene Diphenyl Diisocyanate

MDI stands for Methylene Diphenyl Diisocyanate, an aromatic diisocyanate widely used as a key raw material in polyurethane manufacturing. It is commonly used in rigid PU and PIR foam, insulation panels, adhesives, sealants, elastomers, footwear systems and engineered materials.

For B2B buyers, MDI is typically selected based on grade, NCO specification, viscosity, application suitability, packing and supply consistency. Manufacturers and procurement teams use different MDI grades depending on whether the requirement is for foam, adhesive, elastomer or other polyurethane systems.

In simple terms, MDI helps manufacturers produce strong, durable and performance-oriented polyurethane materials for demanding industrial applications.
