Abstract
When a minor amount of an oxide, hydroxide or basic salt of certain metals from Group 2a of the Periodic Table of the Elements is introduced into the formulation for low density flexible and semiflexible hot-molded flame-retardant polyetherurethane foam compositions which also contain finely-divided solid chlorine-containing polymeric resins, zinc oxide (ZnO) and antimony trioxide (Sb.sub.2 O.sub.3), and optionally a chlorinated paraffin, the resulting foams can be prepared commercially with good reproducibility and good stream stability, and the foams produced are free or essentially free of uncured areas and do not exhibit crumbly or powdery portions.
