How to improve the waterproof and breathable performance of ePTFE membrane?

1. Optimize the microstructure of the membrane
Adjust the stretching process: By controlling the parameters such as the strength, speed and temperature of the stretching, change the size, shape and distribution of the membrane's micropores to achieve a more ideal waterproof and breathable balance.
Improved ablation treatment: Accurately control the conditions of ablation to make the micropore structure more uniform and finer, thereby enhancing the waterproof performance while maintaining good breathability.
2. Surface modification treatment
Chemical coating: Apply a special chemical coating, such as a hydrophobic coating, to the surface of the membrane to improve the waterproof performance without affecting the breathability.
Plasma treatment: Use plasma to treat the membrane surface to improve its surface energy and chemical properties and enhance the waterproof and breathable performance.
3. Multilayer composite structure
Compound with other materials: Compound the ePTFE membrane with materials with specific properties (such as high-performance waterproof coatings, breathable fabrics, etc.) to form a multilayer structure to comprehensively improve the waterproof and breathable effects.
4. Control production process parameters
Strictly control environmental parameters such as temperature, pressure, humidity, etc. during the production process to ensure the stability of the quality and performance of the membrane.
5. Material innovation
Develop new ePTFE material formulas to improve the molecular structure and performance of the material, thereby improving the waterproof and breathable performance of the membrane.
