NEW DEVELOPMENTS IN FLAME RETARDANT POLYURETHANES

摘要

A literature overview over last 5 years on new developments in rigid and flexible PU foams, PU based coatings and TPUs is presented. Although phosphorus-halogen or halogen-containing flame retardants are still the basis for PU industries, there is a trend towards development of halogen-free systems. New high efficient all-phosphorus and non scorching flame retardants for flexible PU foams developed at Akzo Nobel Functional Chemicals are presented.
