PTFE Membrane filter cartridge
Home PTFE Membrane Filter
PVDF (Polyvinylidene fluoride) pleated filter cartridges are high-performance filtration elements designed for applications requiring exceptional chemical resistance, high thermal stability, and superior mechanical strength. These cartridges are widely used in industries such as pharmaceutical, biotechnology, chemical processing, food and beverage, and ultrapure water treatment.
Made from hydrophobic or hydrophilic PVDF membrane and polypropylene components, PVDF pleated cartridges offer excellent resistance to aggressive chemicals, including acids, bases, and solvents. Their pleated design provides high filtration surface area, ensuring long service life and consistent flow rates.
Key Features of PVDF Pleated Filter Cartridge
✅Excellent Chemical Resistance: Suitable for harsh chemicals, acids, and bases.
✅Thermal Stability: Can withstand temperatures up to 90–120°C depending on construction.
✅Low Extractables: Ensures purity of filtrate, ideal for critical applications.
✅High Flow Rate: Pleated structure maximizes surface area and flow efficiency.
✅Wide Compatibility: Compatible with most sterilization methods including autoclaving and hot water.
✅Hydrophilic & Hydrophobic Options: Tailored for different filtration needs (e.g., aqueous vs. gas filtration).
✅Wide Micron Range: Available from 0.1 μm to 10 μm.
✅FDA-Compliant Materials: Suitable for food, beverage, and pharmaceutical use.

Our PP Pleated Filter Cartridges cartridges are:
Constructed with FDA-compliant materials
Tested under strict quality control standards
Available for OEM branding and private label packaging
If you’re looking for a durable, cost-effective, and efficient liquid filtration solution, our PP pleated filter cartridges are an excellent choice.
PVDF offers exceptional chemical resistance compared to PES, Nylon, or PTFE membranes. It can filter aggressive acids (like nitric, hydrochloric) and bases (like sodium hydroxide) without degradation.
PVDF membranes maintain performance even under elevated temperatures. This makes them suitable for hot chemical processes or autoclave sterilization.
These cartridges are manufactured in cleanroom environments and exhibit low protein binding and minimal extractables, ensuring that filtrate purity is not compromised—critical in pharmaceutical and electronic applications.
The pleated construction provides high dirt holding capacity and flow rates, reducing maintenance frequency and operational downtime.
When selecting a PVDF pleated cartridge, consider the following factors:
Filtration Pore Size: Choose 0.22 μm or 0.45 μm for sterile filtration; 1–10 μm for prefiltration or particulate removal.
Fluid Characteristics: Is the fluid acidic, basic, or contains solvents?
Temperature Requirements: Ensure the cartridge supports your system’s temperature.
System Configuration: Match end caps and gasket materials with your housing.
Need help selecting the right filter? Contact our team for technical support.
Always pre-flush the cartridge with clean water or compatible solvent before use.
Check the housing seal to prevent leakage.
Ensure compatibility of O-ring material with your filtration fluid.
PVDF cartridges can be sanitized with hot water or chemical agents. However, actual reusability depends on application, contaminant type, and cleaning protocol.
Store in a clean, dry environment away from direct sunlight. Avoid freezing.
