Hydrophilic PTFE Pleated Membrane Filter Cartridge

Product Overview

The Hydrophilic PTFE Pleated Membrane Filter Cartridge is a high-performance filtration product designed for demanding applications. Utilizing modified polytetrafluoroethylene (PTFE) hydrophilic membrane as the core filtration material, it combines the exceptional chemical resistance of PTFE with hydrophilic properties. With outstanding sterilization efficiency, extreme corrosion resistance, and ultra-low adsorption characteristics, this cartridge is widely used in pharmaceuticals, biopharmaceuticals, electronics (ultrapure water), chemical industries, and laboratories, ensuring reliable high-purity process liquid filtration.

Key Features

✅ High-Efficiency Sterilization & Particle Retention

✅ Hydrophilic PTFE membrane offers precise pore size control (0.1µm, 0.22µm, etc.), effectively retaining bacteria, particles, and colloids to ensure sterility.

✅ Superior Chemical Resistance

✅ PTFE material withstands strong acids, alkalis, organic solvents, and oxidizers (e.g., concentrated sulfuric acid, hydrofluoric acid). Suitable for a broad pH range (1-14), ideal for corrosive liquid handling in chemical and laboratory applications.

Hydrophilic Properties

The PTFE hydrophilic membrane has excellent wettability, enabling rapid water passage and making it ideal for filtering aqueous solutions.

✅ High-Temperature Resistance & Repeatable Sterilization

· Withstands temperatures up to 121°C (moist heat sterilization), supports multiple autoclaving cycles and steam-in-place (SIP) sterilization, reducing consumable replacement costs in sterile production processes.

✅ High Flow Rate & Low Pressure Drop

· Pleated membrane structure maximizes effective filtration area, coupled with PTFE's low flow resistance, enabling high throughput and minimal pressure loss for enhanced filtration efficiency.

✅ Long Lifespan & Mechanical Durability

· PTFE membrane exhibits excellent tensile and tear resistance, maintaining integrity under high-pressure differentials and pulsating conditions, extending service life and lowering total cost of ownership.
