3.Polyether polyol for rigid PU
foam
|
|
|
Polymer composed of initiator (EDA, sorbitol, sucrose, glucoside,
mannitol, triethanolamine, glycerine) and PO.
Features &
Application
The product is mainly used for producing PU foam, and
widely used in refrigerator, refrigeratedcar, freezer, heat-insulating board,
coating, disinfector cabinet, thermal pipes, construction areas etc. The made
products have low thermal conductivity factor and excellent dimensional
stability. It is also an important material for premixed polyol.
