CHANGZHOU, China – Jiangsu LongMembrane High-Tech Co., Ltd., a national high-tech enterprise and recognized provincial "Specialized and Sophisticated" manufacturer of advanced membrane separation products, has introduced its Ultra-clean PES Pleated Cartridge Filter for Sterile Filtration, a high-performance filtration device engineered for demanding pharmaceutical liquid filtration, bioprocessing, and high-purity fluid applications. As global sterile filtration markets expand at a compound annual growth rate exceeding 10%, the product is positioned to serve biopharmaceutical manufacturers, contract research organizations, and electronics industry clients requiring reliable bacterial retention, low protein binding, and repeated steam sterilization capability.
Jiangsu LongMembrane High-Tech Co., Ltd. was established in April 2018 and is headquartered in the Wujin National High-Tech Industrial Development Zone, Changzhou, Jiangsu Province. The company occupies over 45 mu (approximately 3 hectares) and operates fully automated production lines integrating membrane sheet manufacturing, membrane element assembly, and high-end intelligent equipment production. With an annual membrane production capacity exceeding 20 million square meters—ranking among the top three in China—the company employs over 100 staff, including more than 30 R&D technicians. LongMembrane holds ISO9001, ISO14001, ISO45001, GJB 9001C, and multiple other management system certifications, and has led the development of national industry standards for reverse osmosis membrane technical requirements. The company's products are exported to India, Southeast Asia, the Middle East, and other regions, with established long-term partnerships with numerous large state-owned enterprises.
The Ultra-clean PES Pleated Cartridge Filter is engineered as a high-end precision hydrophilic filtration element. The core filter media utilizes a polyethersulfone (PES) membrane, while the drainage layer, housing, end caps, and center rod are manufactured from imported ultra-clean polypropylene materials. Sealing rings are available in multiple options including silicone, fluororubber, and EPDM to accommodate diverse chemical compatibility requirements. Each 10-inch cartridge delivers a filtration area of no less than 0.6 m², with the pleated structure effectively enhancing contaminant holding capacity and flow throughput.
The filter features strong inherent hydrophilicity enabling immediate water passage without pre-wetting, resulting in low flow resistance, improved filtration efficiency, and reduced pump energy consumption. Every cartridge undergoes 100% membrane integrity testing before shipment, ensuring reliable and consistent retention performance. The product offers low protein binding and low extractables, with excellent biocompatibility that minimizes the loss of active pharmaceutical ingredients in drug solutions. Manufactured and packaged in a Class 1,000 cleanroom environment, the filter meets high cleanliness standards and withstands over 100 cycles of 121°C/30-minute saturated steam sterilization. Endotoxin levels are below 0.25 EU/mL, and all materials comply with USP Class VI medical-grade biological safety standards.
The filter operates at a maximum continuous use temperature of 80°C, with forward pressure resistance of 0.42 MPa and reverse pressure resistance of 0.24 MPa at 25°C. It is widely applied in ultra-pure chemical reagent purification, terminal fine filtration in electronic water treatment systems, and is particularly suitable for pharmaceutical and food & beverage industries, precisely retaining bacteria and fine particulates while minimizing protein adsorption loss.
The global PES microporous membrane folding filter cartridge market was valued at USD 765.4 million in 2025 and is projected to grow to USD 1.23 billion by 2034, registering a CAGR of 5.3%. The sterile filtration market is projected to reach USD 9.57 billion in 2026 and is expected to continue growing at a CAGR of 12.02%, reaching USD 19.17 billion by 2032. The polyethersulfone membrane filters market is projected to reach between USD 1.2 billion and USD 2.5 billion in 2025, with a CAGR of 5% to 10% through 2030. Key market drivers include stringent regulatory requirements in the biopharmaceutical industry for drug safety and purity, rising demand for high-quality processed water in the food and beverage sector, and the expansion of the electronics industry requiring ultra-pure water for manufacturing. The Asia-Pacific region, particularly China, is experiencing the fastest growth due to rapid industrialization and increasing investments in pharmaceutical and electronics manufacturing.
The Ultra-clean PES Pleated Cartridge Filter for Sterile Filtration is now available through Jiangsu LongMembrane High-Tech's distribution channels for biopharmaceutical manufacturers, research institutions, electronics manufacturers, and industrial filtration system integrators worldwide, providing a high-performance, cleanroom-manufactured, and integrity-tested filtration solution for critical sterile fluid applications.
