<P>PROBLEM TO BE SOLVED: To provide a molded article using styrene-butadiene copolymer resin which is inexpensive, is suitable for mass production of the molded article, and has rich flexibility, high transparency, radiation resistance and high impact resistance. <P>SOLUTION: This styrene-butadiene copolymer resin molded article is an openable transparent closed container which uses the styrene-butadiene copolymer resin, has the thinnest portion of ≥0.2 mm thickness in a hinge, and is produced by integrally molding the main body and the lid. The styrene-butadiene copolymer resin molded article is used as a medical equipment container 2 or a tool used in a physicochemical test. A middle container is sealed with a sheet, or is packed in a bag and then sterilized with radiations. A slide glass is simultaneously molded together with circular concaves, has a structure that the concaves can be closed with a lid integrally molded through a hinge, and is simultaneously sterilized. The lenses, lens frame and side frames of spectacles are integrally molded from the styrene-butadiene copolymer resin. An injection molding machine is set to a cylinder temperature of 240 to 285°C and to an injection speed of low speed to middle speed. Window glass, lighting fitting cover, tableware, roof tile, helmet or the like is integrally molded from the styrene-butadiene copolymer resin. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
