This is a product made from porous PTFE. It is available in sheet, tube, and punched shapes. It has waterproof and water-repellent functions while maintaining breathability and moisture permeability due to its many pores. 【Sample Offer】 If you would like a sample, please contact us with the number of the desired product listed below. 1) Porous film 100W × approximately 300L - SEF-010 2) Composite porous film A4 size each - PET non-woven composite SEF-501N - PET mesh composite SEF-501M 3) Porous tube 100L each 1×2/2×3/3×4 【Characteristics】 ■ Usable even in high-temperature environments ■ Waterproof and water-repellent effects (some oil-repellent types are also available) ■ As it is made of pure PTFE, it does not degrade due to various chemical liquids ■ Porous films can be manufactured as products laminated with non-woven fabrics, glass cloth, adhesives, or punched processing 【Applications】 ◇ Medical devices ◇ Filters ◇ Air vents ◇ Oxygen sensors ◇ Wire insulation ◇ Thermal insulation materials ◇ Gas vents for ECUs and headlights *For more details, please refer to the PDF document or feel free to contact us.

C-Porous TM porous film (ePTFE) is a product made by porosifying PTFE and forming it into a film. It possesses both air permeability and water repellency, making it suitable for use in filtration filters, oxygen sensors, gas vents, and more. Products that are compounded with non-woven fabric, glass cloth, or adhesives, as well as punched products, can also be manufactured. 【Characteristics】 ◇ Usable in high-temperature environments. ◇ Waterproof and water-repellent effects. ◇ As a pure PTFE product, it does not deteriorate due to various chemical solutions. ◇ Products laminated with non-woven fabric, glass cloth, or adhesives, as well as punched products, can also be manufactured. *For more details, please download the PDF or contact us.

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
