Abstract

PURPOSE: To provide the title stabilizer of high thermal stability and good electrical insulating properties, comprising a tribasic lead sulfate having extremely fine crystals, low bulk density, and high X-ray intensity ratio.
CONSTITUTION: The objective stabilizer comprising a tribasic lead sulfate which has the following characteristics: (1) number average diamefer: ≤0.2μ (2) bulk dansity: ≤1.8g/ml (3) X-ray intensity ratio R (=I3.27/I3.09): ≥7 where I3.27 and I3.09 are intensities of the X-ray diffraction patterns at d=3.27Å and d=3.09Å, respectively. The stabilizer of this invention is practically used in the form of an uniform mixture consisting of it (A) and an inorganic filler (B) in a weight ratio (A):(B) of 95:5W30:70.
