大塚化学 List of News Articles

Otsuka Chemical has started publishing "KATACHI Story column articles." Otsuka Chemical has previously provided "materials" in forms such as powders and liquids, before they become parts. From now on, we will continue to take on new challenges beyond our previous business scope by leveraging the power of materials and our core technologies. One initiative launched as part of this is the "KATACHI Business." This goes beyond mere material sales; by transforming materials into product groups like parts, we create new value. This new endeavor is referred to as "KATACHI Business." In our promoted "KATACHI Business," we provide comprehensive solutions aimed at solving our customers' challenges, not just material provision. Second column: "Basic Knowledge of Super Engineering Plastics Processing! Applications, Types, Heat Resistance Temperatures, etc." We will provide a detailed explanation of the basics of super engineering plastics processing, their diverse types, each of their heat resistance temperatures, and specific applications in a wide range of fields, including the semiconductor and electronic components industries. For more details, please visit our company's website's KATACHI Story through the related link.

Otsuka Chemical Co., Ltd. has recently developed a new separation membrane device for the purification process in antibody drug manufacturing as a result of its alliance agreement with Toyobo Co., Ltd. By adopting this separation membrane device instead of the conventional column chromatography method, it is possible to reduce the number of steps in the purification process by one-fourth, contributing to increased productivity. Sample provision for pharmaceutical manufacturers and research institutions began at the end of April. Antibody drugs are pharmaceuticals that utilize antibodies with the property of binding to specific antigens. They can be designed to target and attack cells or molecules with antigens that cause diseases, offering high therapeutic effects and reduced side effects. The market is expected to expand at an annual rate of approximately 15% until 2030.

Otsuka Chemical Co., Ltd. has recently jointly developed a virus removal membrane for the purification process in the manufacturing of biopharmaceuticals as a result of its alliance agreement with Toyobo Co., Ltd. By suppressing membrane clogging through Toyobo's unique membrane fabrication technology and our polymer technology, the permeation rate of the drug solution per unit time has increased to approximately twice that of Toyobo's conventional products. This has allowed us to reduce the processing time in the virus removal step to less than one-third, contributing to improved productivity. Starting at the end of April, we have begun providing samples to pharmaceutical manufacturers and research institutions.

Otsuka Chemical and its joint development partner U.M.I exhibited their jointly developed sheet material "Polysera" for the first time at the 15th Fine Processing EXPO, a specialized exhibition for micro and precision processing technology, held at Tokyo Big Sight for three days starting January 22, 2025.
