Technical Parameters
eptfe membrane for heat-insulating fabrics
Huzhou Kaili's ePTFE (expanded Polytetrafluoroethylene) membranes are engineered specifically for integration with heat-insulating textiles. By leveraging the unique microporous structure of fluoropolymers, our membranes provide a critical barrier that manages heat while allowing moisture vapor to escape, ensuring both safety and comfort in extreme environments.

Core Technical Advantages
- Extreme Temperature Resistance: Maintains structural integrity and flexibility across a wide thermal range, from -190°C to +260°C.
- Superior Breathability: The microporous structure features billions of pores per square inch, which are 700 times larger than a water vapor molecule, allowing for efficient perspiration management.
- Hydrophobic & Oleophobic: Naturally repels water and oils, protecting the underlying insulation layers from contamination and moisture-induced thermal loss.
- Chemical Inertness: Highly resistant to acids, alkalis, and organic solvents, making it ideal for industrial protective wear and specialized covers.
- Flame Retardancy: Inherently non-combustible, providing an added layer of security for heat-insulating applications.
