ている。2. Description of the Related Art Conventionally, vinyl chloride resin compositions are excellent in physical properties such as impact resistance and heat resistance, and chemical properties such as solvent resistance, acid resistance and alkali resistance.
It is used in a wide range of applications such as pipe materials. In particular, among the uses of pipe materials, the demand for sewerage is expected to continue to increase due to reasons such as environmental improvements. The standard of the vinyl chloride pipe used for sewerage is specified by JIS, but earnest studies are being conducted to provide products that meet the standard more efficiently, more beautifully, and at lower cost. .

る。When the amount of the lead-based stabilizer added is small, the heat stabilizing effect is small, so that decomposition and coloring occur, and when the amount is more than a certain amount, the heat stabilizing effect is saturated.
Since gelation of the vinyl chloride resin slows down and the appearance and physical properties deteriorate, 1 to 100 parts by weight of the vinyl chloride resin is used.
It is limited to 8 parts by weight, preferably 2.5 to 6 parts by weight.

It is possible to express a gray color satisfying The shape, particle size, surface treatment state, etc. of the white filler are not particularly limited,
The average particle size is preferably 0.1 to 30 μm, because the smaller the particle size, the more easily the particles scatter when the raw materials are added or mixed, and the larger the particle size, the worse the appearance of the molded article.
