EPTFE Membrane Waterproof Membrane Filter Membrane 1500mm Width
This EPTFE Membrane combines a breathable Waterproof Membrane structure with a nano-grade non-woven Filter Membrane in 1500mm width.
ePTFE / PTFE Waterproof & Breathable Microporous Membrane
A seller-described ePTFE/PTFE microporous membrane designed around waterproof and breathable performance characteristics, with a listing width of 1500 mm and a selected variation measuring 1.5 m × 0.67 m.
Microporous PTFE Material for Technical Applications
The product is presented as an ePTFE/PTFE waterproof and breathable membrane. The seller also describes it as a microporous membrane and uses “nano-grade non-woven filter membrane” wording in the listing title.
According to the seller description, ePTFE membrane offers excellent chemical stability, resistance to strong acid and alkali environments, and a broad temperature tolerance.
These characteristics can make PTFE membrane material useful as a technical component where the final product design requires a combination of barrier performance and vapor or air permeability. Exact suitability depends on the membrane specification required by the intended application.
Key Features
Waterproof Membrane
The seller markets the material as a waterproof membrane for technical applications where a liquid-water barrier is required.
Breathable Structure
The listing also describes the membrane as breathable, indicating its intended use where moisture-vapor or gas transfer characteristics are important.
Microporous Construction
The material is specifically identified by the seller as a microporous ePTFE/PTFE membrane.
Chemical Stability
Seller description text states that ePTFE has excellent chemical stability and can withstand strong acid and alkali corrosion.
Temperature Tolerance
The seller also describes the membrane as having a wide temperature tolerance. No numerical operating temperature range is supplied in the screenshots.
1500mm Width Wording
The product title specifies a 1500 mm width. The selected piece shown on the product page is 1.5 m × 0.67 m.
Functional Characteristics
Seller-Described ePTFE Manufacturing Process

Handling & Cutting
Handle the membrane carefully to avoid puncturing, tearing, contaminating or permanently creasing the microporous surface.
Use clean cutting equipment and a protected work surface when preparing pieces for further fabrication or testing.
Application Verification
Before incorporating the membrane into a finished product, verify the required thickness, pore structure, permeability, waterproof performance, temperature range, chemical compatibility and bonding method for the intended system.
Adhesives, heat, pressure and lamination processes may affect the final performance of a microporous membrane.
Packing List
