Diphenylmethane Polyphenylene Isocyanate Diisocyanate-Diphenylmethane MDI PM-200

WANNATE PM-200 is a diisocyanate-diphenylmethane(MDI)-based composition containing some higher functionality isocyanates. The functionality is about 2.6-2.7. It is a brown liquid at ambient temperatures.

polymeric diphenylmethane diisocyanate 99%

WANNATE PM-200 can be widely used in the production of rigid PU foam heat-insulating materials; also used in isocyanurate foam, paints, adhesives, structural foam, cellular integral skin foam, automotive bumper and interior parts, high-resilience foam and synthetic wood, etc.

Due to its unique composition structure, WANNATE® PM-200 can provide better flowability. It is, therefore, particularly suitable for the production which require strict flowability of systems.

Since WANNATE® PM-200 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product.

• Containers must be absolutely dry and carefully sealed after congested with nitrogen
• Store indoors at ambient temperature (15-35℃) in a well-ventilated area
• Protect from frost (storage below 5℃ may lead to crystallization)
• If crystallization occurs, heat drum in a hot air oven at 70-80℃ to melt, then thoroughly agitate before use
• Avoid extended storage at temperatures above 50℃
