Product Description

PU Spray foam raw material MDI MR200

■

Application Overview: MR200 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.

■

Key Features: MR200 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.

■

Enhanced Flowability: Due to its unique composition structure, MR200 can provide better flowability. It is, therefore, particularly suitable for production which require strict flowability of systems.
