Barium/Cadmium Carboxylates are among the oldest PVC stabilizers.

Liquid Barium/Cadmium stabilizers with less than 5% cadmium content were developed more than 30 years ago for the stabilization of plasticized PVC They contained a large amount of solvent. At the beginning of the 1970s it was possible to manufacture self-lubricating liquid Ba/Cd stabilizers. At the same time, by using long - Chain fatty acids it was possible to reduce the solvent content. These stabilizers often contain a small amount of Zinc compound to give an improvement in initial color. Furthermore, addition of Zinc carboxylate lowers the sensitivity to discoloration caused by the sulphur-containing substances in the atmosphere. In comparison with the first generation stabilizers, these new stabilizers have improved plate out behavior.
