How membranes are made: excellence and innovation at UBE’s Sakai facility
Applications and technologies
Have you ever wondered how membranes are made? Membranes are a key technology for biomethane production, as they separate gases, removing CO₂ and impurities. UBE, one of Japan’s leading chemical companies, produces these membranes in-house at its Sakai facility using molecular technology. UBE’s first membrane was delivered in 1989, and since then applications have expanded globally, supporting the transition toward a carbon-neutral society. To meet growing demand, UBE has enhanced polyimide production, fiber spinning, and module assembly, increasing overall production capacity by about 1.8 times. The company continues to innovate, embodying its corporate purpose: “Breaking through with the chemistry of hope.”
