Product Description

Product Description

Polymethylene Polyphenylene Isocyanate

Polymethylene Polyphenylene Isocyanate (PMPPI), commonly known as polymeric MDI, is a high-functionality isocyanate mixture consisting of oligomeric structures with multiple reactive NCO groups. This technical product typically contains a blend of diisocyanates and higher oligomers, providing enhanced crosslinking density and mechanical properties in polyurethane formulations.

As a crucial raw material in polyurethane manufacturing, PMPPI serves as the primary isocyanate component in rigid foam production for construction insulation, refrigeration systems, and industrial applications. Its high functionality contributes to superior dimensional stability, thermal insulation performance, and structural strength in final products. Additionally, PMPPI finds important applications in wood composite binders, automotive parts, marine flotation materials, and specialty coatings. The product's versatility allows formulators to achieve specific performance characteristics including improved flame retardancy, enhanced adhesion, and optimized processing parameters. Available in various viscosity grades and NCO content specifications, PMPPI offers reliable reactivity and compatibility with diverse polyol systems for both conventional and advanced polyurethane applications.
