ABSTRACT:
A non-toxic liquid stabilizer comprising, (a) from about 5 to about 35 percent of zinc resinate, (b) from about 5 to about 35 percent of calcium resinate, (c) from about 10 to about 40 percent of non-toxic plasticizer, (d) from about 1 to about 10 percent of a non-toxic antioxidant, and (e) from about 25 to about 75 percent of a non-toxic phosphite, said stabilizer containing from about 0.1 to about 3.5 percent zinc, and from about 0.025 to about 2.28 percent calcium, all weights being based upon the total weight of the stabilizer, is disclosed. Also disclosed is a similar stabilizer which does not contain phosphite and contains from about 25 to about 90 percent of the plasticizer. A method for stabilizing halogenated hydrocarbon resins utilizing the stabilizers of the present invention is also disclosed.
