DiffuLayer™ Waterproof Breathable Membrane DiscWaterproof Breathable Membrane Disc
A circular waterproof breathable membrane disc designed for gas–liquid interfaces, electrochemical devices, air electrodes, and compact research assemblies. The product uses a compact disc format with a current standard specification of Φ10 mm diameter and 1.6 mm thickness, suitable for experimental assemblies and structural validation requiring small-scale gas pathways and liquid blocking.

Product Overview
The compact circular-disc design is convenient for direct integration into research fixtures, gas-line interfaces, and miniature gas–liquid interface structures.
DiffuLayer™ waterproof breathable membrane discs are supplied in a circular sheet format for experimental devices that need gas pathways and liquid-blocking interfaces within limited space. The current standard specification is 10 mm in diameter and 1.6 mm thick.
The product is a compact dark-gray circular disc suitable for direct placement in small test chambers, gas-path structures, or experimental fixtures.
“Waterproof breathable” describes the intended functional role of the product. Actual liquid-blocking capability, gas transmission, and long-term stability are affected by the liquid system, pressure differential, temperature, compression state, and assembly structure. Where quantitative performance is required, use data measured under the applicable test conditions.
Gas–Liquid Interface Function
The functional concept is “liquid-side blocking + gas-side pathway.” Actual performance still depends on the experimental medium and pressure conditions.
Liquid Blocking
Suitable for experimental structures where direct liquid penetration through the membrane should be reduced, helping establish a relatively stable gas–liquid separation interface.
Gas Pathway
The porous breathable structure can serve as a gas-phase transport pathway for studies involving air, oxygen, or other experimental gases.
Compact Interface
The Φ10 mm disc is suitable for compact fixtures, miniature test cells, and structures requiring precise installation positioning.
Key Features
Standard Circular Disc
The standard Φ10 mm circular disc is convenient for matching compact experimental structures.
1.6 mm Thickness
The current product uses a standardized thickness of 1.6 mm.
Gas–Liquid Interface Use
Suitable for experimental structures that require both gas pathways and liquid blocking.
Multiple Pack Quantities
Available in packs of 10, 20, and 50 pcs for single experiments or repeated batch testing.
Core Specifications
Only currently confirmed specification data are shown. Values such as waterproof pressure, gas permeability, and porosity are not estimated where supporting test data have not been provided.
Standard Sizes & Pricing
All current packages use the same Φ10 mm diameter and 1.6 mm thickness; the primary difference is the number of pieces per pack.
| Diameter | Thickness | Package Quantity | Price (USD) |
|---|---|---|---|
| Φ10 mm | 1.6 mm | 10 pcs | $16 |
| 20 pcs | $30 | ||
| 50 pcs | $63 |
Typical Research Applications
Gas–Liquid Interface Research
For research on small-scale gas/liquid separation, mass transfer, and interfacial stability.
Air-Electrode Structures
Can be used as a functional membrane disc in air-electrode and related gas-pathway structures.
Electrochemical Devices
Suitable for gas–liquid isolation studies in small electrolytic cells, reactors, and experimental fixtures.
Structural Validation
The standard circular format supports rapid installation for prototyping and multiple parallel experiments.
Selection & Handling Guide
Check Installation Diameter
Confirm that the fixture or chamber is compatible with a Φ10 mm circular membrane disc.
Confirm Thickness Clearance
The product thickness is 1.6 mm; confirm available chamber and compression clearance.
Validate Experimental Medium
For new liquid systems or high pressure-differential conditions, first perform small-sample liquid-blocking and gas-transmission tests.
Maintain Consistent Assembly
For parallel experiments, keep compression, placement orientation, and fixing method consistent.
For research projects requiring defined breakthrough pressure, gas-flow performance, pore size, or long-term liquid resistance, use an appropriate test method under the actual operating conditions.
