Introduction
Polymeric MDI is generally used in manufacturing hard and semi-hard polyurethane foam.Polymeric MDI is liquefied in normal temperature and easily handled and stored down to -20ºC . It is solvent-free form with2.7 average organic function and maximum of 220cps(25ºC) viscosity which is mixed with monomer MDI of 4,4-diphenyl m-ethane diisocyante and its oligomer above dimer,trimer and tetramer.
The Main Brands are Whanhua PM200 / Bas f M20S / Kumho M200 /Covestro Desmodur 44V20L /Huntsman 2607 and So on
Application
Isocyanates MDI is extensively application in most of field, such as thermal insulation rigid foam, PU coating, PU adhesive, Seepage-proofing, structure foam, Automobile bumper, high resilience etc. With good performance such as very good fluidity, very good foaming capacity, strength well, dimension stability etc.

Shelf Life 
6 Months-12 Months From Manufacturer Date
Storage
Polymeric MDI is supplied in tank cars,tank trucks, and drums. Once a container has been opened, care should be taken to exclude moisture. The most favorable temperature for storage is 15-35°C. If stored at higher temperatures, or if moisture is not excluded, an undesirable increase in viscosity will occur. Below 15°C, the product becomes difficult to pump and pour. Below 0°C, crystallization may occur.
Generally ,the shelf life is 6 months if the temperature is maintained at 15-35°C and moisture is excluded
