POLYMERIC MDI
Chemical Name: Polymethylene Polyphenyl Polyisocyanate CAS No.9002-86-2MF:CH2-CHCl-]nEINECS No.208-750-2Place of Origin:China,Korea
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.
Products Usage
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.

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.
The shelf life is 6 months if the temperature is maintained at 15-35°C and moisture is excluded
