Product Description

Polymeric Mdi PM400
Application
WANNATE® PM-400 is high functionality, high viscosity isocyanate which has a functionality of 2.8~2.9. It can be used the producti
on of rigid PU foam and polyisocyanurate foams; particularly fit for continuous production of laminated polyisocyanurate slabstock foams. WANNATE^® PM-400 can improve cell homogeneity and dimensional stability of foams and the compressive strength vertical to the foaming direction. The flame retardancy of polyurethane and polyisocyanurate foams also shows some improvement.

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 (15-35ºC) in a well-ventilated area. Storage at low temperature (below5ºC) 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 70-80ºC 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 50ºC is not recommended to prevent from the formation of insoluble solids and viscosity increase.
Shelf Life
Under recommended storage conditions, the shelf life of WANNATE^® PM-200 is one year since the date of production.
