At room temperature, WANNATE PM-700 is a dark brown transparent liquid with a functional group of 3.0-3.1 and a NCO content of 29.0-32.0%.
WANNATE PM-700 is the core raw material for the production of polyurethane and polyisocyanurate (PIR) rigid foams.

WANNATE PM-700 is suitable for the continuous production of PIR sandwich panels and can effectively improve the uniformity of foam cell structure, dimensional stability, and the compressive strength in the vertical direction of foaming.
At the same time, WANNATE PM-700 can enhance the flame retardancy of the foam.

WANNATE PM-700 is a high-quality raw material in the field of insulation.
WANNATE PM-700's packaging is a 210L standard steel drum, with a net weight of 250kg per drum.

WANNATE PM-700 should be stored under recommended conditions of 15-35ºC, sealed, dry, and protected from water.
The shelf life can reach 1 year.

WANNATE PM-700 is widely used in the production of insulation hard foams for building exteriors, cold storage, and pipelines, and can also be used in the production of related polyurethane products such as industrial adhesives and composite board bonding.

WANNATE PM-700 is a polymeric methylene diphenyl diisocyanate (MDI) with higher functionality.
WANNATE PM-700 was specifically designed for use in the production of both PUR and PIR (continuous and discontinuous) block foams.

The slightly higher functionality and intermediate viscosity of WANNATE PM-700 also makes it ideal for certain continuous and discontinuous laminating processes.
The increased functionality promotes improved foam cure, excellent strength properties and better dimensional stabilities.
