Product Desciption
POLYMERIC MDI 44V20L/PM200 /MR 200/ 5005S
Application
44V20L is a diisocyanate-diphenylmethane(MDI)-based composition containing some higher functionality isocyanates. The functionality is about 2.6-2.7. It is abrown liquid at ambient temperatures.
44V20L 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, 44V20L can provide better flowability. It is, therefore, particularly suitable for the production which require strict flowability of systems...
Typical Physical and Chemical Properties
Package(s)
210L iron drums, 250kg/drum
Storage
Since 44V20L 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 44V20L 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 44V20L is one year since the date of production.
