Expanded polytetrafluoroethylene (EPTFE) is produced through a fluorine-free biaxial stretching process, using water-based dispersants instead of traditional PFOA/PFOS, combined with recycled PTFE raw materials (more than 30% recycling ratio) to form a 0.1-5μm controllable microporous structure. While maintaining waterproof and breathable (>15,000g/m²·24h moisture permeability, >20,000mmH₂O hydrostatic pressure), it meets the environmental protection standards of the entire life cycle (from production to recycling) and has passed Bluesign®, OEKO-TEX® Standard 100 and ISO 14067 carbon footprint certification.
Product Advantages
Fluorine-free environmentally friendly process
Green chemical synthesis: Use short-chain fluorinated compounds to replace long-chain PFAS (EPA 537.1 detection limit <1ppb), pass REACH Annex XVII and EU PFAS ban pre-compliance.
Low-temperature production: process temperature <200℃ (traditional PTFE requires 380℃), energy consumption reduced by 40%, carbon footprint <5kg CO₂e/kg (ISO 14067).
Circular economy innovation
Recycled EPTFE blending: 30% recycled PTFE + 70% virgin material, mechanical properties retained >95% (ASTM D638), moisture permeability maintained >12,000g/m²·24h.
Chemical recycling technology: supercritical CO₂ depolymerization process (efficiency >90%), recycled material purity >99% (GC-MS detection).
Functionality and environmental protection synergy
Self-cleaning surface: Nano titanium dioxide coating (photocatalytic decomposition of pollutants), reducing washing frequency and water consumption (saving 60% water).
Bio-based adhesive: Use plant-based PU adhesive (carbon content>30%), heat seal strength>25N/cm (ASTM F88).
