Description
Technical Parameters
eptfe membrane film for multilayer fabrics
 

At Huzhou Kaili New Material Technology Co., Ltd., we specialize in the coating, finishing, and customization of ePTFE membrane films for multilayer fabrics, providing textile manufacturers with a high-performance functional layer engineered for demanding applications.

Our ePTFE membrane film is designed to integrate seamlessly into two-layer, 2.5-layer, and three-layer fabric systems, delivering reliable breathability, protection, and durability while maintaining fabric comfort and flexibility.

 

Role of ePTFE in Multilayer Fabric Systems

Modern performance textiles rely on multilayer construction to combine comfort, protection, and mechanical strength. Our expanded PTFE membrane film acts as the critical functional barrier layer, positioned between face fabrics and linings or backers.

Its microporous structure allows:

  • Water vapor molecules to escape efficiently
  • Liquid water, wind, and external contaminants to be blocked

This controlled permeability makes it ideal for advanced fabric architectures.
