Abstract
PVC stabilizers containing an overbased mixture of salts, such as magnesium and zinc salts, of unsubstituted and/or alkyl-substituted benzoic acid and optionally one or more fatty aliphatic acids, which contain a carbonate and/or silicate stabilizer, and which preferably also contain one or more polyols containing 2 to 10 hydroxyl groups, exhibit significant and unexpected reduction in the tendency to volatilize and form 'fog' upon exposure of the formulation to moderately elevated temperatures, without loss of other desirable stabilization properties.
