In the search for safer and more sustainable materials, flame-retardant tecAs the global demand for sustainable energy accelerates, the safe and efficient storage of hydrogen and other compressed gases has become a key technological challenge. UBE, a Japanese multinational founded in 1897, applies its long-standing expertise in advanced polymers to deliver innovative solutions that meet the industry’s highest standards for performance and reliability.
At the core of this innovation are UBE’s high-performance polyamide materials specifically engineered for Type IV pressure vessels, advanced storage systems used for hydrogen and compressed gases. These lightweight vessels combine exceptional mechanical strength with excellent barrier properties, ensuring long-term safety under extreme pressure and temperature conditions.
UBE has developed a specialized portfolio of UBE Nylon polyamide (PA) grades, including 1218IU, 5033IU / 5033IU50, 1230IU4, and 1230IU6, suitable for injection, blow molding, and extrusion processing. Each grade is designed to balance mechanical stability, optimal processing, and gas impermeability, addressing the diverse needs of mobility and industrial applications.
The materials demonstrate superior hydrogen and methane barrier performance, high drawdown resistance, and outstanding tensile strength, even at very low temperatures. These properties make UBE’s polyamides an optimal choice for high-pressure storage systems where integrity and long-term reliability are critical. Their proven performance has been validated by major automotive manufacturers such as Toyota and Hyundai, confirming their suitability for next-generation hydrogen mobility.
Through advanced polymer design and processing expertise, UBE delivers materials that redefine safety, efficiency, and sustainability in compressed gas storage — supporting the global shift toward cleaner energy and hydrogen-powered solutions.
