Fire -retardant polyurethane foam and process for preparing the same

摘要: A process for preparing a polyurethane foam that contains particles of expandable graphite and halogenated fϊre-retardant additive which surprisingly impart excellent properties to the provide stable isocyanate -reactive component having improved pot life industrial scale production purposes. The can be prepared by mixing single isocyanate-reactive containing additives along with all polyols other ingredients an in two-component machine such as high-pressure device applying reaction mixture into suitable container.
