一般特征
DESMOPHEN 1159 S N is an inactive trifunctional polyether modified with a styrene-acrylonitrile (SAN) polymer with a solid content of approx. 10% by weight. 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.
