Blend of flame retardants with reduced halogen content for the preparation of flexible polyurethane foams having low emission

摘要

Mixtures of (A) hydroxyalkyl phosphonates and (B) chlorinated phosphate esters. An Independent claim is also included for a method for the production of flame-resistant flexible polyurethane foam by reacting organic polyisocyanates with compounds containing at least 2 isocyanate-reactive hydrogen atoms, plus the usual blowing agents, stabilisers, activators etc., in presence of components (A) (halogen-free) and (B).
