Product Description
Polyol TDI and Other Chemicals Making for Upholstery Furniture Polyurethane Foam Sponge Raw Materials
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.
It 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, it can provide better flowability. It is, therefore, particularly suitable for the production which require strict flowability of systems.
