Expanded polytetrafluoroethylene (EPTFE) is formed into an ultra-fine pore structure of 0.05-0.2μm through a nano-scale biaxial stretching process, achieving extreme lightweight with a gram weight of <50g/m² (single-layer membrane) while maintaining waterproofness and breathability (hydrostatic pressure>25,000mmH₂O, moisture permeability>15,000g/m²·24h), redefining the performance boundaries for ultra-light outdoor equipment (tents, sleeping bags, and jackets).
Product Advantages
Nano-scale structure optimization
Single-layer microporous membrane: 0.1μm pore water-blocking layer + 0.2μm breathable layer integrated stretching, no need to laminate multiple layers (traditional process requires 3 layers), gram weight directly reduced by 50%.
Glue-free lamination: Laser welding technology replaces glue bonding, eliminating the weight of the glue layer (5-10g weight reduction per square meter), peel strength>40N/cm (ISO 13935-2).
Ultra-thin high-strength fiber
Nanofiber reinforcement: PTFE fibril diameter <0.1μm (SEM verification), tensile strength>80MPa (ASTM D882), strength/weight ratio super carbon fiber.
Gradient support design: high longitudinal fiber density (tear resistance), loose transverse fibers (moisture permeability), and balanced dynamic performance.
Environmentally friendly and lightweight
Recycled EPTFE blend: 30% recycled PTFE + 70% virgin material, carbon footprint <3kg CO₂e/kg (ISO 14067), strength retention rate >98%.
Degradable auxiliary materials: plant-based PU coating (biodegradation rate >90%, ASTM D5511), total weight <5g/m².
