Optimized silicone surfactant for the manufacture of flame retarded foams
von Dr. Annegret Terheiden, Dr. Roland Hubel
For many applications flexible polyurethane foam has to meet certain flammability requirements. Therefore special formulations are required which include the use of flame retardants, modified polyols and also the proper choice of silicone surfactants. In the past, Evonik has put a lot of resources into the development of tailor-made highly sophisticated FR silicone surfactants which are optimized regarding their impact on flammability as well as their processing in combination with different types of flame retardants and different types of polyols (hydrophilic, natural oil-based polyols or standard polyols). A new FR surfactant is presented which meets the requirements of a broad range of FR foam grades, including different polyols, FR additives, conventional blown foams and CO<sub>2</sub>-blown foams.
