Notes:
Molybdenum-based compounds are effective smoke suppressants for rigid and flexible polyvinyl chloride formulations, both unfilled and filled with calcium carbonate and alumina trihydrate. These compounds, two of which are new compounds based on zinc molybdate with or without a phosphite synergist, are useful as is or extended onto core materials such as clay or talc. The addition of molybdenum-containing additives to flexible PVCs containing antimony trioxide usually raises the oxygen index and thus improves flame retardancy. Tests indicate that molybdenum acts as a flame and smoke suppressant in the solid phase.
