DESCRIPTION
HG006 is a compounded polyether polyol developed for refrigerators and freezers. It is developed to be used with mixture of cyclopentne,is and HFC-245fa as blowing agent. It contains polyether polyol, silicone surfactant, catalysts and water.
It does not contain any physical blowing agent, therefore the addition will be done before foaming the product.

The above testing data have been generated in lab or field conditions which are typical for this application. They are believed to be correct but data variations due to varying processing or ambient conditions can not be excluded. The customer remains responsible for making his own interpretation of data and suitability of the chemicals to his particular operation.
Handling and Storage
LYR113MA should be protected from moisture by keeping containers sealed when not in use. Drums have to be stored indoors to protect the material from water ingress, frost and direct heat from the sun. Under temperature conditions and in properly sealed containers ,the storage life of the polyol is 6 months.
The optimum storage temperature should be 10-30ºC.

POLYMERIC MDI 44V20L/PM200 /MR 200/ 5005S
Blend Polyol and Polymeric Mdi 44V20L for Rigid Insulation FoamApplication
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...

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.
