| High Light | Fluorine Free PFAS Free Membrane ，PFAS Free Membrane Breathable ，Waterproof Membrane PFAS Free | ||
This is a roll-form, PFAS-free and fluorine-free waterproof breathable membrane designed for converters and large-scale manufacturers. The film is completely free of intentionally added PFAS and is manufactured in a controlled, fluorine-free production environment. It provides high air permeability and water barrier performance, available in custom thicknesses from 0.10 to 0.50 mm. The membrane is suitable for lamination, die-cutting, and ultrasonic welding. It serves as the core functional layer in vent plugs, adhesive patches, and acoustic vents for a wide range of industries.
Converters and OEMs need a bulk supply of breathable membrane that can be further processed into finished vent components. The supply chain must now be PFAS-free to meet EU and US regulatory deadlines. However, most ePTFE rolls are inherently PFAS-containing. Changing to a PFAS-free substrate should not force converters to alter their existing tooling, lamination processes, or adhesive compatibility. A drop-in alternative in roll format is essential.
We produce a fluorine-free breathable membrane roll using a proprietary extrusion and stretching process. The film exhibits isotropic air permeability and can be wound on 3-inch or 6-inch cores. Thickness can be specified to match existing die-cut parameters. Surface treatments allow excellent adhesion to acrylic, silicone, or rubber-based adhesives. The membrane meets IP67 waterproof standards and has passed automotive heat aging tests. It is supplied on moisture-proof packaging ready for cleanroom conversion.
Ideal for adhesive vent patch converters, acoustic vent manufacturers, automotive tier-1 breather plug producers, and electronics enclosure makers who laminate membrane in-house. The roll format supports high-speed rotary die-cutting, kiss-cutting, and lamination lines.
The roll is loaded onto an unwind station. Converters can laminate it with a chosen adhesive film and die-cut it into desired shapes. The membrane’s micropores, formed during the biaxial stretching process, remain fully functional after conversion. When integrated into a vent plug or patch, it allows air and vapor transport while blocking water, exactly as ePTFE does but without fluorinated chemistry.
Define your required roll length, width, and core size. Select thickness based on your die-cut process: thicker films for deeper kiss-cut, thinner films for high-density packing. Request a small trial roll to verify lamination bond strength and die-cut edge cleanliness. We offer technical support to optimize your conversion process around this new film.
Q: Is the surface corona-treated for adhesive?
A: Yes, we apply a custom surface treatment to achieve a dyne level above 42, ensuring robust adhesive bonding.
Q: Can you slit rolls to narrower widths?
A: We can slit to as narrow as 50 mm with accurate edge guiding for your automated lines.
Q: What is the shelf life of the roll?
A: 24 months when stored in original packaging at 20–25°C and 50% RH.
Q: How do I test PFAS-free status on the roll?
A: We provide a certificate with each batch. You can also send samples for total fluorine analysis to verify <10 ppm.
