Product Description

WANNATE^® MDI-50 is a mixture of 2,4’ and 4,4’ diphenylmethane diisocyanates, or called 2,4’ rich isocyanate. It is a clear, colorless to pink liquid at ambient temperatures.

Specification

Application

WANNATE^® MDI-50 is a mixture of 2,4’and 4,4’diphenylmethane diisocyanates, or called 2,4’rich isocyanate. It is a clear, colorless to pale yellow liquid at ambient temperatures. Due to the different reactivity between 2,4’and 4,4’MDI, WANNATE^® MDI-50 provides better flow ability for the production of injection molding. WANNATE ^® MDI-50 can be widely used in the production of various PU elastomers, adhesives, paint and automotive parts. It also can be used as a substitute for TDI in the production of flexible PU foam, which will reduce productive cost and environmental pollution and improve handling conditions.

Package

210L iron drums, 235kg/drum

Storage

Container: Freshly manufactured WANNATE^®MDI-50 is a clear liquid at room temperature. It tends to turn yellow upon exposure to air and light. As WANNATE^® MDI-50 is a reactive chemical; reaction with atmospheric moisture occurs easily and leads to the formation of MDI-50 Version：V 6.0 2 / 3 Date of issue: Mar.1,2017 insoluble urea and CO2 gas which can lead to pressure build-up in closed containers and increases in the viscosity of the product. Containers must therefore be absolutely dry and carefully sealed after congested with dry nitrogen. Temperature: Extended storage will result in insoluble dimer. It is best to store at 15℃-40℃.

Shelf Life

Under recommended storage conditions, the shelf life of WANNATE^® MDI-50 is 6 months since the date of production.
