Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Filtration And Membranes. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This hydrophobic microporous filtration membrane is made from 100% expanded polytetrafluoroethylene (ePTFE). Its interconnected fibril microstructure is designed for particle retention while allowing gas flow.
The listed pore-size range is 0.02–10 μm, enabling buyers to select a grade according to the required filtration duty. Reported construction options include unreinforced membrane and customizable reinforcement using PET or non-woven fabric.
The product is described as gas-permeable, with high breathability and low flow resistance. Listed operating temperature is -200°C to 260°C, while reported waterproof grades are IP67 and IP68. Buyers should confirm whether these ratings apply to the membrane itself or to a finished, properly integrated assembly.
Available technical grades include nominal pore sizes of 10, 5, 1, 0.45, 0.22, 0.1, 0.05, 0.03, and 0.02 μm. Reported minimum bubble point rises from greater than 0.1 bar for the 10 μm grade to greater than 7.0 bar for the 0.02 μm grade. Reported flow rate at 7 k.
Pa ranges from greater than 5,500 ml/cm²·min for the 10 μm grade to greater than 150 ml/cm²·min for the 0.02 μm grade. Thickness and maximum available width vary by grade.
Listed application areas include pharmaceutical chemistry, electronic-grade processes, panels, semiconductors, medical consumables, electronics, automotive uses, and packaging. These are stated application categories rather than confirmation that every membrane grade is qualified for every process.
Before procurement, confirm the required pore size, thickness tolerance, roll or sheet format, usable width, reinforcement, target flow rate, bubble-point test method, and chemical exposure.
Buyers should also request evidence that the selected configuration meets their cleanliness, shedding, waterproofing, temperature, regulatory, and process-validation requirements.
Compatibility with the intended housing, sealing method, sterilization or reprocessing cycle, and actual liquid chemistry should be established for the final assembly before production use.
