Jiangsu Jushuo Advances ALK PPS Diaphragm Technology

ZHANGJIAGANG, JIANGSU, CHINA, October 23, 2026 /CourierPR/ -- Jiangsu Jushuo New Materials Technology Co., Ltd., a leading manufacturer of specialized polymer materials, has announced advancements in its ALK PPS diaphragm technology. This development is crucial as the company aims to meet the growing demand for advanced materials in industrial applications, particularly in hydrogen production and environmental protection.

ALK PPS diaphragms are specialized components used in alkaline water electrolysis, a process essential for hydrogen production. These diaphragms play a critical role by separating gases generated during electrolysis while facilitating ionic transport through the electrolyte. The performance of these diaphragms is influenced by several factors, including material structure, wettability, pore distribution, and mechanical strength. Jiangsu Jushuo's focus on these aspects ensures that its diaphragms meet the stringent requirements of industrial environments.

Polyphenylene sulfide (PPS) is a high-performance polymer known for its heat resistance, chemical resistance, and dimensional stability. When engineered into a suitable textile or composite structure, PPS can withstand challenging operating conditions. However, the performance of a PPS diaphragm is not solely determined by the polymer. The design process involves careful consideration of fiber characteristics, fabric construction, surface properties, pore structure, and post-treatment processes. This comprehensive approach ensures that the final product meets the specific needs of the electrolyzer in which it will operate.

In the context of hydrogen production, the ALK PPS diaphragm is a key component that balances several critical requirements. Adequate ionic conductivity is essential for minimizing electrical resistance, while effective gas separation helps reduce unwanted mixing of gases. Mechanical integrity and chemical stability are also vital as the diaphragm operates in a demanding environment over repeated cycles. Jiangsu Jushuo's expertise in material engineering allows it to address these challenges through a range of approaches, including adjustments in fiber selection, weaving parameters, fabric density, surface treatments, and composite structures.

Testing plays a crucial role in the development and evaluation of diaphragm products. Jiangsu Jushuo conducts relevant evaluations to measure surface resistance, wettability, tensile strength, dimensional stability, chemical resistance, and gas separation characteristics. Long-duration testing provides valuable insights into the material's performance under sustained operating conditions. This rigorous testing ensures that the diaphragms are suitable for specific electrolyzer designs and meet the high standards required in the industry.

Beyond hydrogen production, Jiangsu Jushuo's advanced polymer materials are also significant in other industrial applications. For instance, in the industrial flue-gas filtration industry, high-performance polymer materials are essential for managing particulate matter and other contaminants in exhaust streams. PPS fibers are used in certain filtration applications due to their heat resistance and chemical properties. The design of filter media requires careful consideration of fiber selection, fabric construction, and surface treatment to ensure optimal filtration efficiency, pressure drop, and service life.

The fire-resistant protective garment industry is another field where high-performance materials are critical. Jiangsu Jushuo's expertise in material engineering enables it to develop specialized textiles that provide thermal protection while maintaining flexibility, strength, comfort, and durability. The selection of materials for protective garments is closely linked to the specific risks associated with the intended workplace. Jiangsu Jushuo ensures that its products meet the relevant fire-resistance and thermal-protection standards through rigorous testing and certification processes.

In summary, Jiangsu Jushuo New Materials Technology Co., Ltd., through its advancements in ALK PPS diaphragm technology, demonstrates its commitment to meeting the evolving needs of industrial applications. By focusing on material engineering and rigorous testing, the company ensures that its products are reliable and performant in demanding environments.
