Product Description
Polyphenylene Isocyanate Diisocyanate-Diphenylmethane MDI PM-200
1, General Description
WANNATE PM-200 is a diisocyanate-diphenylmethane(MDI)-based composition
containing some higher functionality isocyanates. The functionality is about 2.6-2.7. It is a
brown liquid at ambient temperatures.

4, Application:
WANNATE PM-200 can be widely used in the production of rigid PU foam
heat-insulating materials; also used in isocyanurate foam, paints, adhesives, structural foam,
cellular integral skin foam, automotive bumper and interior parts, high-resilience foam and
synthetic wood, etc. Due to its unique composition structure, WANNATE® PM-200 can
provide better flowability. It is, therefore, particularly suitable for the production which
require strict flowability of systems.
5, Storage properties:
Since WANNATE® PM-200 is a reactive chemical, reaction with atmospheric moisture
happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which
can result in pressure build-up in closed containers and viscosity increase of the product.
Containers must therefore be absolutely dry and carefully sealed after congested with
nitrogen.
Containers of WANNATE® PM-200 should be kept properly closed and stored indoors at
ambient temperature (15-35℃) in a well-ventilated area. Storage at low temperature (below
5℃) may lead to some crystallization; this material must, therefore, be protected from frost.
If crystallization does occur, the material should be heated by rolling the drum in a hot air
oven at 70-80℃ to melt it out, and should then be thoroughly agitated before use. Melting in
a water bath is not recommended.
Extended storage at temperatures above 50℃ is not recommended to prevent from the
formation of insoluble solids and viscosity increase.
6, Handing precautions:
Product may cause skin and eye irritation. In cases of skin contact wash
immediately with soap and water. For eyes, flush with plenty of water for 15
minutes and seek medical attention immediately.
Under recommended storage conditions, the shelf life of WANNATE® PM-200 is one year
since the date of production.
