Molded flexible polyurethane foams with reduced flammability and superior durability

摘要

The present invention provides a process for producing a flexible polyurethane foam achieving reduced flammability and maintaining durability is presented. These foams are prepared by reaction of a di- or polyisocyanate/polyisocyanurate blend with polyol component optionally in the presence of a catalyst, a blowing agent, additives and a cross-linking agent. The polyisocyanurate used in the blend is a novel composition.
