Polymeric MDI WANNATE PM-200 CAS NO 9016-87-9 Used in Polyurethane Foam
1.Application
WANNATE PM-200 is a diisocyanate-diphenylmethane (MDI)-based composition containing some higher functionality isocyanates. It is a brown liquid at ambient temperatures.
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 flow ability. It is, therefore, particularly suitable for the production which require strict flow ability of systems.

4.Storage
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.
5.Shelf Life
Under recommended storage conditions, the shelf life of WANNATE PM-200 is one year since the date of production.
