The present invention provides an injection molding resin composition capable of producing a molded article having excellent thermal stability and thermal fluidity and having high water pressure resistance, without using heavy metals such as lead and tin, and A molded body using the resin composition for injection molding is provided. The present invention is a resin composition for injection molding containing a chlorinated vinyl chloride resin, a vinyl chloride resin, and a heat stabilizer, wherein the heat stabilizer contains a calcium alkylcarboxylate and a zinc compound. The vinyl chloride resin has a polymerization degree of 400 to 1000, and contains 1 to 30 parts by mass of vinyl chloride resin with respect to 100 parts by mass of the chlorinated vinyl chloride resin. It is. |
