[Also in Division Cl] Barium silicate coated with alkaline earth metal soaps of fatty acids containing at least 6 carbon atoms (see Division Cl) is used in vinyl halide resin compositions to prevent stickiness. Vinyl halide resins specified are homopolymers of vinyl chloride, bromide fluoride and vinylidene chloride, and copolymers thereof with vinyl acetate, vinylidene halide, ethyl methacrylate and methyl methacrylate. Also present in the composition may be stabilizers e.g. lead, barium, cadmium, zinc and tin salts, and plasticizers, e.g. phthalates, adipates, azelates, sebacates, phosphates, ester epoxides, polyethylene glycol esters, and chlorinated paraffins. |
