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
Recommended storage temperature (°C): 15 - 35
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.
Shelf life (ex works)
12 months if stored in sealed, moisture-tight containers
Partially used containers should be tightly resealed due to the hygroscopic nature of the product.
Recommended temperature for processing (°C): 20 - 25.
