PLPT / PLPTH Series PTFE Membrane Filter Cartridge
Product Overview
PLPT / PLPTH Series PTFE membrane filter cartridges are engineered for high-precision filtration of corrosive chemicals, oxidizing liquids, etching solutions, stripping liquids, and other demanding process fluids.
The PLPT series utilizes naturally hydrophobic PTFE membrane, delivering exceptional chemical resistance, corrosion resistance, and stable filtration performance in strong corrosive liquid applications.
The PLPTH series employs modified hydrophilic PTFE membrane, enabling direct liquid filtration without pre-wetting treatment. This reduces operation time, simplifies filtration procedures, and enhances process efficiency.
With high particle retention efficiency, extensive chemical compatibility, and multiple micron rating options, this series is ideal for chemical processing, semiconductor manufacturing, electronics, and high-purity liquid filtration applications.
Key Features
- Excellent Chemical Compatibility: PTFE membrane provides outstanding resistance to strong acids, alkalis, oxidizing agents, corrosive chemicals, etching liquids, and stripping solutions. Suitable for demanding liquid filtration conditions where ordinary filter media may not perform reliably.
- High Particle Retention Efficiency: The PTFE membrane offers excellent particle capture capability with up to 99.99% particle interception efficiency, ensuring stable filtrate quality in precision filtration processes.
- Hydrophobic and Hydrophilic PTFE Options: PLPT series uses natural hydrophobic PTFE membrane for applications requiring strong chemical resistance and hydrophobic performance. PLPTH series uses hydrophilic PTFE membrane for direct liquid filtration without pre-wetting, enabling easier and more efficient operation.
- Multiple Filtration Precision Options: Filtration ratings from 0.01 μm to 10 μm available to meet different process requirements. Customized micron ratings can also be provided according to application needs.
- 100% Integrity Inspection Before Delivery: Each filter cartridge undergoes inspection before shipment to ensure stable quality, reliable sealing performance, and consistent filtration efficiency.
