This hydrophilic PTFE separator membrane exhibits broad chemical compatibility, including resistance to strong acids and strong alkali solutions across pH 1-14. The uncoated expanded PTFE material requires no pre-wetting for aqueous filtration applications.
- Chemical Resistance: The membrane resists degradation in strong acid and strong alkali environments, enabling use with aggressive electrolytes.
- pH Compatibility: The material maintains structural integrity across the full pH range of 1 to 14.
- Wettability: The hydrophilic surface allows direct aqueous wetting without alcohol pre-treatment.
- Material Stability: Expanded PTFE construction provides thermal and chemical stability suitable for battery separator applications.
- Lot Variability: Slight lot-to-lot variations may occur, but performance indicators remain within specified tolerances.
What is the effective pore size and pH compatibility of the PTFE battery separator base film?
The membrane has a nominal pore size of 0.22 μm (with 0.2 and 0.45 μm also listed) and is stable across a pH range of 1–14. This broad pH tolerance, combined with the expanded PTFE structure, makes it suitable for aggressive electrolyte environments common in battery research.
Can this uncoated PTFE membrane be used directly in aqueous battery electrolytes, or does it require pre-treatment?
Although the membrane is supplied as hydrophilic, the handling note specifies that for aqueous filtration, hydrophobic PTFE should be pre-wetted with ethanol or isopropanol before use. This pre-wetting step is essential to ensure proper wetting and to avoid air-locking in aqueous battery electrolyte systems.
What are the key handling and storage considerations for this 60 mm diameter PTFE separator?
The 60 mm diameter, 100-sheet pack is uncoated and should be handled with care to avoid contamination or physical damage. The manufacturer notes that slight variations may occur between production lots, but performance indicators are guaranteed to comply with specifications. For aqueous filtration, pre-wetting with ethanol or isopropanol is required if the membrane is hydrophobic.
This 0.22 μm hydrophilic expanded PTFE separator in 60 mm disc format offers broad chemical resistance (pH 1-14) and suitability for organic solvents, but requires pre-wetting with ethanol or isopropanol for aqueous filtration due to its hydrophobic base nature.
Positive
- Broad chemical and pH compatibility: Resistant to strong acids, strong alkalis, and many organic solvents across pH 1-14, enabling use in aggressive battery electrolyte environments.
- Hydrophilic pre-wetted format: Supplied as hydrophilic membrane, allowing immediate aqueous filtration without additional surfactant treatment, reducing preparation time in lab workflows.
Trade-offs
- Pre-wetting required for aqueous use: Despite hydrophilic designation, the handling note states that hydrophobic PTFE must be pre-wetted with ethanol or isopropanol before aqueous filtration, adding a preparation step.
- Lot-to-lot variation possible: Slight variations may occur between production lots, though performance indicators are guaranteed to meet specifications, requiring batch verification for critical applications.
