PTFE Porous Film - List of Manufacturers, Suppliers, Companies and Products | IPROS GMS

For adjusting differential pressure inside and outside the casing and for degassing applications! PTFE porous film for automotive use.

Achieving both breathability and water-repellent, dust-proof properties!

This is a product that has porous PTFE created using proprietary technology. It retains the properties of fluoropolymer (such as heat resistance, chemical resistance, weather resistance, and electrical properties) while also providing breathability and water repellency. Utilizing its characteristic of allowing air to pass through while blocking water and dust, it can be used for differential pressure adjustment inside and outside enclosures in automotive parts, as well as for degassing applications. Additionally, a type with oil repellency is also available, which maintains stable performance even in harsh automotive environments susceptible to high temperatures, dust, and oil. 【Examples of Applications】 • Gas vent applications for ECUs and headlights • Sound-permeable dust-proof membranes for dash cams and in-car speakers • Waterproof breathable membranes for O₂ sensors 【Reasons for Choosing PTFE】 • Usable across a wide temperature range, including around engines and in cold regions • In addition to dust and water resistance, it can also provide oil repellency, making it suitable for harsher environments • Excellent resistance to automotive oil, with minimal aging degradation, allowing for sustained performance
