Our company exhibited at the 5th Sustainable Material Exhibition during the High-Performance Material Week held from November 12 (Wednesday) to 14 (Friday), 2025. We showcased products that create new business value, primarily featuring the cellulose fiber high-content resin "Green Chip CMF," along with non-combustible and insulating sheets, and products using natural raw materials from our group company, NichiRica. We sincerely thank everyone who visited our booth. Through the display of molded products, "Green Chip CMF" effectively communicated its design and functionality, receiving positive feedback. Additionally, we received specific inquiries regarding thickness adjustments and fire resistance/insulation performance for the non-combustible and insulating sheets, along with numerous requests for sample provision. Furthermore, we exhibited existing NichiRica products along with two new development items. The development items were very well received, and we feel that the possibilities for new applications have expanded. In addition to the exhibited products, we will continue to respond to various needs by utilizing our formulation development technology, evaluation technology, and processing technology while co-creating with our customers.
