AR M200

5005 is a standard functionality polymeric diphenyl methane diisocyanate (MDI).

M20S is a polymeric MDI with a functionality of approximately 2.7. Lupranate M20S is suitable for the production of rigid insulation foams by molding, spraying, and frothing. It is also used for rigid and semi-flexible integral skin foams, adhesives, sealants, elastomers, and high-resiliency flexible foams. In low catalyzed rigid urethane formulations, the foam rise time can be lengthened by 20-30%. The slower reactivity can be advantageous in applications such as large rigid foam panels or molded flexible foams.

5008 is a high functionality polymeric diphenyl methane diisocyanate (MDI).

SR-550 is polymeric MDI, generally used in manufacturing rigid pu foam and polyisocyanurate(PIR) foam. Cosmonate SR-550 is solvent-free form with high functionality of 2.8∼2.9 and minimum of 450 cps (25℃) viscosity.
Especially, Cosmoante SR-550 can improve the dimentional stabilities of foam and the flame retardancy of foam, which has a higher functionality.

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.
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.

Desmodur ® 44V20L is a dark-brown, liquid blend ofdiphenylmethane-4,4′-diisocyanate (MDI) with isomer and homologues ofhigher functionality. It is used in conjunction with polyols to produce rigidpolyurethanes foam.
