摘要

Polyurethane foams flexu00ecveis molded with reduced flammability and superior durability. The present invention provides a process for the production of a flexible polyurethane foam with reduced flammability and maintaining durability.These foams are prepared by the reaction of a mixture of di - or poliisocianato / polyisocyanurate with polyol component, optionally in the presence of a catalyst, expansion agent, additives, and a cross-linking agent. The polyisocyanurate employee in the mixture is a new composition.
