Polymethylene polyphenyl polyisocyanate CAS 9016-87-9

Polyaniline polyisocyanate (PAPI), commonly known as polymerized MDI or crude MDI, CAS 9016-87-9, is a light yellow to brown viscous liquid typically composed of about 50% diphenylmethane diisocyanate (MDI) mixed with 50% higher functional polyisocyanates. It is a key raw material for producing polyurethane rigid foam, widely used in the insulation layer of refrigerators, pipes, and building panels. At the same time, it also has important applications in adhesives, coatings, sealants, and other fields.
