Introduction To Pleated Microporous Filter Cartridges

Pleated microporous filter cartridgesare a kind of precision filter element with polypropylene (PP), polytetrafluoroethylene (PTFE), polyether sulfone (PES) and other materials as the core filter medium. It can achieve high efficiency of retention through the folding microporous membrane structure, and is widely used in industry, medicine, food, and other fields.
The pleated microporous filterseries features a foldable structure made from breakthrough sub-micron, high-performance, ultra-fine polypropylene fiber membrane materials, boasting uniform pore distribution and exceptional filtration performance. The filter cartridge is manufactured using heat-sealed welding technology, ensuring a robust structure without any adhesives.

Filter element common specifications:
Length: 5-40 inches (e.g., 10 inches, 20 inches)
Diameter: 60-131mm
Inner diameter: 28-40mm

Filter cartridge selection suggestions:
Material selection: PTFE is preferred for strong acid and alkali environment, PP is selected for high flow demand.
Precision matching: 0.1-0.45μm for medical grade, 1-50μm for industrial filtration.

Pleated microporous filter cartridge materials and structures:
Made of polypropylene (PP), PTFE, PES and other materials through hot welding process, no adhesive residue, avoid secondary pollution. The folding design significantly increases the filter area, improves the pollution capacity and circulation efficiency.

Pleated microporous filter filter performance:
Accuracy range: 0.1-100μm, can intercept particles, bacteria and other impurities. Strong chemical corrosion resistance, suitable for strong acid, strong alkali and organic solvent filtration. Working temperature: PP filter element: less than 80℃; PTFE filter element: has better high temperature resistance
