Polypropylene Compounds for Automotive Applications Sumitomo Chemical Co., Ltd. Polypropylene Compounds for Petrochemicals Research Laboratory Automotive Applications Satoru MORITOMI Tsuyoshi WATANABE Susumu KANZAKI Engineering plastics and metals have been extensively replaced by polypropylene (PP) based materials in auto- motive parts in order to achieve weight reductions and cost savings. To accomplish this, PP compounds which are made from PP and other components are under intense investigation. In this paper, we review the progress of re- search into compounding technology, improvement of mechanical properties and functionalization. Some problems and solutions for injection molding are also summarized. Furthermore, material developments for environmental load reduction are shown. This paper is translated from R&D Report, “SUMITOMO KAGAKU”, vol. 2010-I. Introduction tion. Therefore, it is expected that PP consumption will continue to increase in the future.

  • Facilitation of Information Transfer on Chemicals in Products
    Facilitation of Information Transfer on Chemicals in Products The Ministry of Economy, Trade and Industry (METI) developed ‘chemSHERPA’ [kémʃéərpə] as a new information transfer scheme for chemicals in products throughout their supply chains. METI hopes that the dissemination of chemSHERPA may contribute to reduce the workload of both providers and recipients of the information. From the beginning of the development of chemSHERPA, METI has been in communication with international bodies such as the IEC and the IPC, etc., with the aim of developing chemSHERPA into not only a Japanese standard but also an International standard. To make it a de-facto standard, METI has introduced this scheme to international organizations and governments of other countries for their active use. The Joint Article Management Promotion Consortium (JAMP) is a governing body for chemSHERPA from April 2016 and see a shift to chemSHERPA. We believe many companies are preparing towards implementing chemSHERPA. Based on the efforts mentioned above, the following companies and company groups have agreed with the dissemination of chemSHERPA, and METI will continue to work with JAMP and companies to spread the use of chemSHERPA to internal as well as external supply chains as needed.(Please contact us if any company or company group has interest in putting its name below.) It should be noted, the use of the provision of data entry support tools is free of charge in principle with the aim of promoting wider use of chemSHERPA.

    Safety Evaluation Study Using Sumitomo Chemical Co., Ltd. Environmental Health Science Laboratory Embryonic Stem (ES) Cells Nobuyuki HORIE Hashihiro HIGUCHI Satoshi KAWAMURA Koichi SAITO Noriyuki SUZUKI Embryonic stem (ES) cells are pluripotent stem cells that have the capacity for self-renewal and multilineage differentiation, and they have recently started to be used in the safety evaluation of chemicals. The novel in vitro embryotoxicity test (EST) that utilized the differentiation ability of mouse ES cells into cardiomyocytes was established in Germany. We could obtain results which were equal to the validation study performed in Europe and will apply the test system to a preliminary assessment of new chemicals. In addition, we have par- ticipated in one of the national projects to improve this test system to make it much simpler and more precise.
