About Daicel Arai Chemical
Daicel Arai Chemical is a chemical company founded in 1981, based in Myoko, Niigata Prefecture (Japan), and part of the Daicel Group. In addition to basic chemicals such as acetic anhydride and cellulose acetate, the company mainly produces electronic materials, including resist polymers for semiconductor manufacturing, optical light-source materials such as LED encapsulation materials, and chiral separation columns (Kiral columns) for pharmaceutical research. Further product areas are pharmaceutical active ingredients and pharmaceutical intermediates, fermented products, and inorganic materials such as nanodiamond and silver nano ink (prototype production). The service portfolio also includes product inspection, research and development (experiments, analysis) and the maintenance of machinery and electrical systems. The Innovation Center Arai (iC-A), completed in 2018, serves as a hub for development work. The site traces back to the Arai plant of the Daicel Group founded in 1935.
