Two-component polyurethane / vinyl ester hybrid foam system and its use as a flame retardant material and material for filling openings in buildings with foam

摘要: A two-component polyurethane/vinyl ester hybrid foam system is formed of a polyol component (A), which contains at least one polyol, catalyst for the reaction with polyisocyanate, polymerizable vinyl monomer and water or blowing agent on basis compressed liquefied gas as foam-forming agent, polyisocyanate (B), polymerization monomer, designed use flame retardant material filling openings, cable pipe bushings in walls, floors and/or buildings purpose fire protection.
