Introduction:
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 the 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.
Application:
Polyether polyols' major use is in polyurethane foams. Flexible foams are primarily used in cushioning applications such as furniture, bedding and car seats, and in carpet underlay. Rigid foam's largest consumer is the construction industry where it is mostly used for insulation. Rigid foam is also used in commercial refrigeration and packaging. Smaller uses for polyether polyols include elastomers, adhesives and sealants, surface coatings and polyurethane fibres.
