ePTFE Electronic Membrane

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.

Product Features

• Excellent Chemical Resistance: Resists acid, alkali, and extreme environmental conditions.
• Stable Microporous Structure: Small, uniform pore size with a porosity of over 80%.
• Outstanding Waterproof and Breathability: Achieves IPX8 waterproof rating while allowing gas permeation and sound transmission.
• Strong Mechanical Properties: Good strength and compression resistance, suitable for various electronic product applications.
• Multifunctional: Serves as both a pressure balance membrane and an electronic sound transmission membrane, offering dual functionality.

Applications

• Electronics: Used in electronic devices for waterproofing and sound transmission, particularly in mobile phones, speakers, and other similar products.
• Sealing and Protection: Provides sealing protection for electronic devices, helping to regulate internal pressure changes.
• High-Quality Sound Transmission: Used as an electronic sound membrane to enhance sound quality.
• Waterproof Materials: Applied in various electronic products requiring waterproof capabilities.
