Technical Analysis and Application of Shanghai Xulun Polypropylene Folding Filter Cartridge
Date: 2025-07-28Read: 9
1、 Product Core Features
1. Material and process advantages
Made of ultra-fine polypropylene fiber film through hot melt welding, without adhesive, ensuring no release of chemical pollutants. The folding structure enables a single 10 inch filter element to have an effective filtration area of 0.7 square meters, which is 5-8 times more efficient than traditional filters.
2. Performance parameters
The filtration accuracy covers a gradient range of 0.1-50 μ m, meeting the requirements of pharmaceutical sterile filtration (0.22 μ m) to chemical pre filtration (50 μ m)
• Temperature resistance up to 80 ℃ (working)/120 ℃ (instantaneous sterilization), pressure resistance of 0.3MPa, suitable for high-pressure steam sterilization process
2、 Highlights of Technological Innovation
1. Gradient filtering structure
The outer layer is made of coarse non-woven fabric to intercept large particles, while the inner layer is made of nano-sized PP film for fine filtration, increasing the pollutant holding capacity by 300%.
2. Hot melt sealing technology
The end cap and center rod are made of medical grade PP material through hot melt welding to eliminate the risk of leakage, and have passed FDA certified integrity testing.
3、 Typical application scenarios
1. Biopharmaceutical field
Used for injection sterilization filtration (0.22 μ m) and purification of culture medium in vaccine production, in compliance with GMP sterile requirements.
2. Food and beverage industry
In mineral water terminal filtration, particles ≥ 1 μ m can be intercepted 100%, extending the service life of RO membrane by more than three times.
3. Electronic chemical processing
Excellent corrosion resistance to semiconductor wet electronic chemicals (such as hydrofluoric acid), with a metal ion retention rate of ≥ 99.8%.
