Begin with materials development
Jinlun and Gongyuan describe a development approach that connects membrane-grade resins, fibers, yarns and separator fabrication. The company brochure places this work within more than 20 years of polyarylene sulfide research at Tiangong University, focused on membrane and fiber materials for energy and environmental applications.
For the hydrophilic PPS separator, the relevant manufacturing chain connects PPS resin, fibers, yarns and separator fabrication. This materials-to-separator approach provides the context for the company’s work on wetting, gas separation, ion transport and mechanical support.
Connect fibers and yarns to separator structure
The brochure reports specialized PPS resins and fiber modification technologies, including the development of hydrophilic fibers. It also describes low-torque ring spinning to obtain PPS yarns with low twist and low hairiness.
At the separator stage, micropore control is described as supporting industrial production of woven separators with low resistance and high gas barrier performance. Chemical bonding between support and composite layers addresses functional-layer delamination. These statements describe the manufacturer's development work; they are not a universal performance guarantee for every product or operating condition.
Link development with customer requirements
The brochure presents coordination across raw materials, processing and separator fabrication as a way to connect materials research with end-use needs. Quality management covers incoming materials, production and finished-product release, with attention to fiber structure, thickness uniformity and alkali resistance.
For customers, the practical next step is a model-specific technical discussion: confirm the separator designation, dimensions, cutting and assembly needs, and applicable test conditions. Agreed technical documents define specifications and delivery criteria, while inspection records and application feedback support further improvement.
