General Characterization
Desmophen 41WB01 is a reactive polyether triol with high polyoxyethylene content. It is not miscible with most polyether polyols (e.g. Arcol Polyol 1108, Arcol Polyol 1374).
Flexible Slabstock Foam Applications:
Desmophen 41WB01 is used among other applications to manufacture hypersoft foam grades with a pleasant supple feel and to produce soft conventional foams.
Flexible Molded Foam Applications:
Desmophen 41WB01 is used in small quantities as cell opener in the production of the flexible polyurethane cold-curing molded foam for automotive seating.

Storage Conditions
Storage in original sealed Covestro containers.
Recommended storage temperature (°C): 15 - 35
Protect from moisture, heat and foreign material.
Partially used containers should be tightly resealed due to the hygroscopic nature of the product.
Long storage or transport at low temperature may lead to a turbid product. Heating up to 30 °C and homogenization will make this turbidity go away without any remaining effect on the quality of the product.
Covestro represents that, for a period of 12 months following the day of shipment as stated in the respective delivery documents, the product will meet the values set forth in section "specification" above provided that the product is stored in full compliance with the storage conditions and is otherwise handled appropriately.
The lapse of this period does not necessarily mean that the product no longer meets specifications. However, prior to using said product, Covestro recommends to test such a product if it still meets the specifications. Covestro does not make any representation regarding the product after the period and Covestro shall not be responsible or liable in any way for the product failing to meet specifications after the period.
Recommended temperature for processing (°C): 20 - 25.
