Abstract

The present invention provides a polyvinyl chloride-based resin molded product obtained by molding a resin mixture containing 3 to 15 parts by weight of calcium carbonate having an average primary particle size of 0.01 to 0.3 µm and 2 to 4 parts by weight of an impactmodifier per 100 parts by weight of a polyvinyl chloride-based resin, wherein a Charpy impact strength at 23°C is 20 kJ/m 2 or more, and a weight reduction ratio is 1.5 mg/cm 2 or less when the molded product is immersed in a 93% by weight sulfuric acid aqueous solution for 14 days in accordance with JIS K 6745, and a method for manufacturing the polyvinyl chloride-based resin molded product.
