Dow PAPI™ 94 Polymeric MDI
Categories:	Fluid; Polymer
Material Notes:	PAPI™ 901 polymeric MDI is a polymethylene polyphenylisocyanate that contains MDI. This products low viscosity, low functionality, increased diphenylmethane diisocyanate content and increased percentage of orthopara isomers make PAPI™ 94 polymeric MDI highly versatile. This product also offers delayed gel times, which results in better flow into molds for semi-flexible and integral skin foams. Information provided by Dow
