Abstract

PURPOSE: To provide the title composition of low lead eluation, having excellent thermal stability, transparency, and dispersibility, for use in chlorine-contg. polymers, which comprises an extremely fine powder of tribasic lead sulfate and an alkaline earth metal-based filler in a specific weight ratio.
CONSTITUTION: The objective composition comprising (A) an extremely fine powder of tribasic lead sulfate having an average size ≤0.2μ (pref. ≤0.1μ) and a bulk density ≤1.8 pref. ≤1.7) g/ml, and (B) a filler consisting of an inorganic compound such as an alkaline earth metal (Ca, Mg, Ba, Sr, etc.) carbonate, silicate, sulfate, phosphate, oxide, hydroxide, etc. in a weight ratio (A):(B) of 95: 5W30:70 (pref. 95:5W50:50). The composition can be obtained by grinding and mixing the above components by means of an atomizer, ball mill, etc. In practical use, the composition would be incorporated in a chlorine-contg. polymer in an amount of 2W15wt% on the basis of the polymer.
