PHOSPHAZENE FLAME RETARDANT POLYCARBONATE COMPOUNDS

摘要

A non-halogenated flame retardant polycarbonate compound is disclosed. The compound comprises a polycarbonate, a non-halogenated, non-migrating, non-plasticizing flame retardant adduct. The compound can achieve a UL 94 rating of V-0 at a thickness of at least 3.2 mm and otherwise achieves no dripping/igniting of the cotton indicator during that test. The adduct is formed from an allyl-functional phenoxyphosphazene and a hydride-functional polysiloxane.
