Polymeric MDI Wanhua wannate PM-200 Used As Polyurethane Foam

1. Application

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.

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.

250kg/drum

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.
