The present invention aims to provide a method for producing a chlorine-containing resin composition and a method for producing a chlorine-containing resin processed product, the methods being capable of providing a processed product that is excellent in thermal stability and heat resistance and that has various excellent properties derived from the chlorine-containing resin in an efficient, easy, simple, and high-yield manner, without degrading the appearance of the processed product. The present invention provides a method for producing a chlorine-containing resin composition, including: step (I) of dry-mixing a silicone oil and/or a liquid fatty acid having a C12 or higher carbon chain with a hydrotalcite powder to obtain a mixture; and step (II) of further mixing a chlorine-containing resin with the mixture.

A composite film material usable in a data carrier card body includes a first outer plastic layer, an inner plastic layer and a second outer plastic layer, all the layers together forming a co-extruded composite. The plastic material of the first outer layer is a polyethylene terephthalate glycol copolymer (PETG) or contains a PETG, the plastic material of the inner layer is a thermoplastic copolyester elastomer (TPC) or contains a TPC, and the plastic material of the second outer layer is a PETG or contains a PETG.

A synthetic roofing tile or panel is provided that includes one or more features enhancing the impact resistance and other desirable properties as well as the ease of installation and/or use of the roofing tile or panel on a building structure. The roofing tile is formed in an improved color variation process is provided with regard to the manufacture of a synthetic material roofing tile in order to effectively simulate the appearance of the natural material represented by the synthetic roofing tile. The roofing tile also can be compression molded such as in a method for manufacturing a synthetic roofing tile or panel is provide in which a number of inserts representing the desired appearance for the roofing tile or panel can be utilized in the manufacturing process to provide roofing tiles or panels with the desired appearance. The inserts can be interchanged within the molds in order to provide different appearances to roofing tiles or panels formed using the same molds.

A composition includes a polycarbonate resin, a heat stabilizer, and an acid stabilizer. An article formed from the composition, when tested using a 2.5 mm color plaque, includes a level of free OH groups that is less than a level of free OH groups of a reference article injection molded from a substantially similar reference composition consisting essentially of the polycarbonate resin without the heat stabilizer and the acid stabilizer. Methods for forming the molded article in accordance with the above are also described.

A balance trainer having a dome and a base formed integrally is provided. Besides, a mold assembly for manufacturing the balance trainer that has a dome mold, a girdle, and a cover is provided. The girdle is sleeved on the dome mold and the cover is fixed on the girdle and thereby a cavity is formed in the mold assembly. Furthermore, a manufacturing process of the balance trainer is also provided. The process has the following steps: preparing ingredients of the dome and the base; feeding the ingredients of the dome into the dome mold; fixing a membrane on the dome mold via the girdle; feeding the ingredients of the base; sealing the ingredients via the cover; and then rotational molding. With the process and the mold, the rotational molding step can mold two materials at the same time, so the product can have two parts with different hardness.
