PM-200 is a diisocyanate-diphenylmethane (MDI)-based composition containing some higher functionality isocyanates. The functionality is about 2.6-2.7. PM-200 can be widely used in the production of rigid PUR foam heat-insulating materials; also used in PIR foam, paints, adhesives, structural foam, cellular integral skin foam, automotive bumper and interior parts, high-resilience foam and synthetic wood.

PM-400 is high functionality, high viscosity isocyanate which has a functionality of 2.8-2.9. It can be used the production of rigid PU foam and PIR foams; particularly fit for continuous production of laminated PIR slabstock foams. PM-400 can improve cell homogeneity and dimensional stability of foams and the compressive strength vertical to the foaming direction. The flame retardancy of PUR and PIR foams also shows some improvement.
