PM-200 is a composition based on diisocyanate diphenylmethane (MDI), containing some highly functional isocyanates. The function is approximately 2.6-2.7. It is a dark brown liquid at ambient temperature. PM-200 can be widely used to produce hard PU foam insulation materials; It is also used in isocyanurate foam, paint, adhesive, structural foam, porous self skinning foam, automobile bumper and interior trim, high resilience foam and synthetic wood, etc. Due to its unique compositional structure, PM-200 can provide better fluidity. Therefore, it is particularly suitable for production that requires strict liquidity of the system.
