Description
Technical Parameters
eptfe membrane for fabric layering technology
 

Huzhou Kaili's ePTFE (expanded Polytetrafluoroethylene) membranes are engineered to be the definitive functional core in high-performance Fabric Layering Technology. In a modern technical garment, the membrane acts as the critical interface-managing the pressure gradient between the body's micro-climate and the external environment.

Produced at our 3,000m² facility in the heart of the Yangtze River Delta fluoromaterial cluster, our membranes provide the structural stability and high-energy surface required for permanent bonding in 2-layer, 2.5-layer, and 3-layer textile composites.

Optimized for Multi-Layer Structures

  • 3-Layer (3L) Hardshells: The membrane is fully protected between a rugged face fabric and a tricot backer for maximum durability in professional mountaineering and tactical gear.
  • 2-Layer (2L) Insulated Systems: Offering a soft hand-feel and high flexibility for lifestyle performance and ski-wear.
  • 2.5-Layer (2.5L) Ultralight: Compatible with specialized "dry-touch" internal prints that protect the ePTFE layer while maintaining extreme packability.
  • Industrial Safety Composites: Laminated with FR (Flame Retardant) and chemical-resistant layers for specialized utility uniforms.
