Desmophen® 1166 S N - for flexible slabstock foams
Desmophen® 1166 S N is an inactive trifunctional polyether modified a styrene-acrylonitrile (SAN) polymer. It is specifically designed for the production of conventional flexible slabstock foams with enhanced loadbearing properties, using CO2-technologies due to its appropiate particle size distribution. It exhibits a broad processing range and allows the use of most commercially available silicone surfactants and tertiary amine catalysts.

Storage Conditions
Recommended storage temperature (°C): 10 - 35
The product must be stored in sealed, moisture-tight containers. Partially used
containers should be tightly resealed, due to the hygroscopic nature 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
