Description
Technical Parameters
eptfe coated membrane for textile lamination
 

Huzhou Kaili provides specialized ePTFE (expanded Polytetrafluoroethylene) membranes designed specifically for high-strength textile lamination. Our membranes are engineered to serve as the functional mid-layer in 2-layer (2L), 2.5-layer, and 3-layer fabric constructions, providing a permanent barrier against the elements while maintaining class-leading breathability.

As a manufacturer within the Kaili Advanced Materials Group, we utilize advanced coating and finishing techniques to ensure our membranes offer superior adhesion and durability for global textile brands.

Engineered for Lamination Excellence

  • High Peel Strength: Our ePTFE membranes undergo specialized surface treatments to increase surface energy, ensuring a powerful mechanical bond with PUR (Polyurethane Reactive) and hot-melt adhesives.
  • Thermal Stability: With a melting point exceeding 327°C, our membranes do not shrink, pucker, or degrade during the high-heat lamination process, ensuring a smooth and aesthetic fabric finish.
  • Uniform Porosity: Precise control over the microporous structure ensures that air permeability and waterproofness remain consistent across the entire width of the fabric roll (up to 2600mm).
  • Chemical & Oil Resistance: Available with oleophobic coatings to prevent "contamination-induced delamination" caused by body oils, salt, and detergents.
  • Bi-Component Compatibility: Designed to work seamlessly with various face fabrics, including Nylon, Polyester, Aramid, and Spandex blends.
