Description
Technical Parameters
eptfe membrane for garment fabric systems
 

Huzhou Kaili New Material Technology Co., Ltd. provides the critical functional layer for the world's most advanced Garment Fabric Systems. Our ePTFE (expanded Polytetrafluoroethylene) membranes are engineered to act as a "second skin," providing an impenetrable barrier against wind and rain while facilitating the rapid transport of moisture vapor away from the body.

From our 3,000m² facility in the Yangtze River Delta fluoromaterial cluster, we specialize in the coating, finishing, and customization of membranes that define the performance limits of professional outdoor, military, and workwear systems.

Integrating Performance into Every Layer

In a multi-layered garment system, the ePTFE membrane is the engine that drives comfort. Our membranes are optimized for:

  • The 3-Layer System (Hardshell): Providing maximum durability by bonding the membrane between a rugged face fabric and a protective inner backing.
  • The 2-Layer System (Insulated): Offering a lightweight, soft-hand feel when laminated to a face fabric and paired with a separate lining or insulation.
  • The 2.5-Layer System (Packable): Utilizing a printed protective "half-layer" on the membrane's interior for ultra-lightweight, high-breathability emergency shells.

 

System-Level Technical Advantages

  • Dynamic Breathability: Features over 9 billion micropores per square inch. These pores are 700 times larger than a water vapor molecule, allowing heat and sweat to escape instantly during high-exertion activities.
  • Total Weather Lock: Provides 100% windproof protection and a hydrostatic head (waterproofness) of up to 30,000mm, far exceeding international standards for extreme weather gear.
  • Oleophobic System Protection: Our membranes can be treated with specialized finishes to prevent the "wet-out" caused by body oils, salt, and detergents, ensuring the garment system remains breathable for years.
  • Thermal Versatility: Remains soft and flexible in sub-zero Arctic conditions (-190°C) and maintains structural integrity in high-heat industrial environments (+260°C).
