PTFE Hydrophobic Microporous Pleated Filter Cartridge

Product Description — PTFE Pleated Filter Cartridge

• The PTFE Pleated Filter Cartridge is engineered with naturally hydrophobic polytetrafluoroethylene (PTFE) membrane and a robust polypropylene support structure, offering exceptional reliability in the most demanding chemical processing environments. Leveraging the superior chemical inertness and corrosion resistance of PTFE, this filter is specifically designed to handle aggressive organic and inorganic solvents, strong acids, strong alkalis, and highly oxidizing fluids where conventional filter materials fail.
• With its advanced pleated construction, the cartridge provides a large effective filtration area, ensuring a long service life, high flow rates, and low differential pressure. The hydrophobic PTFE membrane delivers outstanding microbial retention capability, making the filter ideal for sterilization-grade applications. A hydrophilic PTFE option is also available, suitable for aqueous solutions requiring enhanced wetting performance.
• The cartridge’s thermal stability allows continuous operation up to 80°C under standard conditions, while its mechanical strength ensures consistent integrity even under varying pressure conditions. All components—including support layers, center core, outer cage, and end caps—are constructed from high-purity polypropylene (PP), ensuring broad chemical compatibility and ultra-low extractables.
• Designed for industries that cannot compromise on purity or safety, the PTFE pleated filter cartridge meets stringent cleanliness and biosafety requirements, making it suitable for pharmaceutical manufacturing, fine chemicals, electronic chemicals, high-purity reagents, strong oxidizing agents, and other applications where chemical durability and microbial control are critical.
