FH-501800 polyether polyol is a unique polyol for the production of slabstock and molded viscoelastic foam. It allows for the production of a wide range of viscoelastic foam grades with consistent performance properties along with a lower glass transition temperature that can be tailored to end-use applications. It provides expanded formulation and is designed to offer enhanced processing which promotes good cure of viscoelastic foams.
FH-501800 is typically used as the primary polyether polyol in TDI based formulations to make most combinations of density and firmness grades of slabstock foams. Firm grades may require an addition of a high solids polymer such as FH-50200 polyol. Use of a cell opening polyol may be beneficial for achieving maximum foam porosity. A lower functionality MDI can also be used for processing various viscoelastic foam grades. As with any product, use of FH-201800 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Storage
FH-501800 polyol is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect processing. This product can become quite viscous at low temperatures. For ease of handling, storage temperatures between 15°C (59°F) and 60°C (140°F) are recommended.
The shelf life is twelve months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
