ePTFE Electronic Membrane offers exceptional breathability, superior chemical resistance, and high thermal stability. Designed for electronic components, sensor protection, and industrial filtration applications, it ensures reliable performance, enhanced durability, and optimal environmental protection.
Product Overview
ePTFE electronic membrane is a microporous material made from PTFE resin through a biaxial stretching process. This membrane possesses excellent chemical resistance (acid, alkali), resistance to high and low temperatures, hydrophobicity, and features a fiber-like microporous structure with small and uniform pores, offering a porosity greater than 80%. The ePTFE membrane not only provides waterproof, breathable, and moisture-permeable properties but also serves as a sealing material to maintain pressure balance and temperature variations inside electronic devices, making it ideal for waterproofing and sound transmission applications in electronics.
