Polyether polyols Chemical Structure Composition. Polyether polyols are key components used in the production of polyurethanes. Polyether-based polyurethanes exhibit enhanced hydrolytic stability and excellent resistance to weak acids and bases compared to polyester-based polyurethanes. Polyether polyurethane can be divided into soft foam polyether, rigid foam polyether and elastomer with polyether according to performance of polyether products. However, polyether-based polyurethanes are more susceptible to UV radiation and provide poor resistance to oils and fuels compared to polyester-based polyurethanes.
Production:
Polyether Polyols are made by reacting organic oxide and glycol.
Main organic oxide utilized are Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.
Main glycols utilized are Ethylene Glycol, Propylene Glycol, Water, Glycerine, Sorbitol, Sucrose, THME.
Polyols contain reactive hydroxyl (OH) groups which react with isocyanate (NCO) groups on isocyanates to form polyurethanes.
There are many kinds of polyether polyols for polyurethane. PU materials with different performance can be obtained with the reaction between different initiators and olefin polymerization.
By modifying the PU raw materials or changing the catalyst, polyether performance can be modified. These initiators include diethyl alcohol, ternary alcohol, tetrahydrofuran, and aromatic polyether polyols, etc.
