Osaka Gas believes that technologies serve as the foundation of corporate competitiveness, and considers R&D to be one of the most important elements in the strategy to make a difference.
For this reason, Osaka Gas works actively on R&D and commercialization of new technologies, as presented below.
Daigas Group has been supplying its own unique cellulose fiber (fluorene cellulose) with high dispersibility in resins and organic solvents and which is inhibited from aggregation when dried.
Cellulose fibers have one fifth the weight and five or more times the strength of steel, and one fiftieth the thermal expansion coefficient of glass, and they are promising as a plastic filler material alternative to glass fibers.
Cellulose fibers, however, have high hydrophilicity (high affinity for water), so that water loses its fluidity only with several percentage addition of them in water.
Furthermore, cellulose fibers dispersed in water will aggregate when dried, which makes it difficult to mix with commodity plastics.
Daigas Group modified the cellulose fiber surface by its original material “fluorene derivative,” to develop fluorene cellulose which is unique and useful cellulose fiber material inhibited from aggregation when dried.
Fluorene cellulose, which contains little water and mixes easily with resins such as polylactide (PLA) and polyamide (PA), can be provided in various forms, including dry powder, solvent dispersion for coating applications, and master batch for commodity plastics. Daigas Group is actively providing samples to its customers and receiving a high reputation in various applications.
