What are the reasons why the service life of ePTFE membrane is shorter than expected?

1. Quality issues
Poor quality of raw materials: Low-quality polytetrafluoroethylene raw materials are used, which affects the basic performance and durability of the membrane.
Production process defects: Lax process control during the manufacturing process, such as uneven stretching and unreasonable microporous structure, leads to unstable performance of the membrane.
2. Improper construction and installation
Rough construction: Physical damage such as scratches and tears to the membrane during installation.
Poor fixation: Insufficient fixing points or incorrect fixing methods of the membrane cause the membrane to loosen and shift during use, increasing wear and stress.
Poor splicing and sealing: Improper handling of the splicing, gaps or poor sealing, make it easy for moisture and impurities to invade, accelerating the aging of the membrane.
3. Environmental factors
Extreme temperature: Long-term exposure to high or low temperature environments that exceed the membrane's tolerance affects its physical and chemical properties.
Chemical corrosion: The presence of highly corrosive chemicals in the surrounding environment erodes the structure of the membrane.
Ultraviolet radiation: Long-term exposure to strong ultraviolet rays causes aging and embrittlement of the membrane material.
4. Inadequate maintenance
Lack of regular inspection: Failure to promptly detect damage to the membrane surface, dirt accumulation, and other issues, affecting its normal function.
Improper cleaning method: Using inappropriate cleaning agents or cleaning methods, damaging the surface structure of the membrane.
5. Exceeding the design load
The pressure, humidity and other conditions in actual use exceed the tolerance range of the membrane's original design.
