General Characterization
Desmophen® 1166 is an inactive trifunctional polyether modified a styrene-acrylonitrile (SAN) polymer with a solid content of approx. 25% by weight. It is specifically designed for the production of conventional flexible slabstock foams with enhanced loadbearing properties. 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
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.
