APPLICATION
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.
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.
Pure MDI:
white to yellowish crystal at room temperature, storage temperature below 5 degrees, , packing generally 250 kg iron drum nitrogen filled packaging (tank car nitrogen filled )
Polymerized MDI:
colorless brown liquid, stored at room temperature, shelf life of two years, the packaging is generally 250 kg iron drum nitrogen-filled packaging.
