EPTFE composite fabric is a multifunctional material that combines expanded polytetrafluoroethylene (EPTFE) microporous membrane with a high-strength substrate (such as nylon, polyester, aramid) through hot melt adhesive or lamination process. It has waterproof and breathable (>15,000g/m²·24h moisture permeability, ASTM E96), tear resistance (>50N/mm, ASTM D5587) and chemical protection (EN 14325) properties. It is widely used in outdoor equipment, medical protection, industrial filtration and new energy fields, and meets ISO 13485 medical-grade production standards and Bluesign® environmental certification.
Product Advantages
Composite process innovation
Sandwich structure: outer layer 20D nylon tear-resistant (UV-resistant coating, QUV 5,000 hours retention >90%), middle layer EPTFE membrane (0.1-0.5μm gradient pore size), inner layer skin-friendly mesh (contact angle <10°).
Seamless hot pressing: laser welded seams (peel strength >60N/cm, ISO 13935-2) to avoid interlayer separation caused by glue aging.
Dynamic performance optimization
Humidity responsive breathability: membrane pores automatically open and close with body surface humidity (moisture permeability increases by 40% when humidity >70%), body temperature fluctuation <±2℃ (ISO 7730).
Multi-directional elasticity: composite four-way elastic substrate (stretching rate >180%, ASTM D4964), adapted to high-intensity sports deformation.
Extreme environment resistance
Chemical corrosion resistance: 98% sulfuric acid, 40% hydrofluoric acid (EN 374-1, penetration time>8 hours).
Abrasion and scratch resistance: Nano ceramic coating on the surface (Mohs hardness>8), Martindale wear resistance>100,000 times (EN 530).
