ePTFE membrane substrate
At Huzhou Kaili New Material Technology Co., Ltd., we specialize in the design and production of ePTFE membrane substrates - advanced base materials engineered to deliver superior performance in filtration, protective apparel, and industrial applications. Located in Huzhou, Zhejiang Province - the heart of China's Yangtze River Delta fluoromaterial industry cluster - our 3,000-square-meter facility integrates R&D, coating, and finishing capabilities under one roof.
As a member of Kaili Advanced Materials Group, we are dedicated to advancing fluoropolymer technologies that meet the growing global demand for high-performance composite fabrics.
Product Overview
The ePTFE membrane substrate serves as the foundation layer in laminated or coated composites, providing the structural integrity and functional balance between breathability, waterproofness, and chemical stability. Manufactured through advanced stretching and sintering processes, our substrate features a uniform microporous structure that combines mechanical strength with precise air and moisture vapor permeability.
Key Features:
- Superior Microporous Structure – Optimized pore distribution ensures high breathability and consistent performance under pressure.
- Excellent Chemical Resistance – Resistant to acids, alkalis, and solvents, ideal for harsh industrial or laboratory environments.
- Thermal Stability – Performs reliably across a wide temperature range (-200°C to +260°C).
- High Tensile Strength – Engineered for lamination, coating, and composite applications requiring mechanical durability.
- Customizable Surface Treatments – Available in hydrophobic, oleophobic, or plasma-treated versions depending on client needs.
