High vapor transmission film for functional product needs
High vapor transmission film for functional product needs
Overview
High breathable waterproof TPU (Thermoplastic Polyurethane) film provides a perfect balance of waterproofness and moisture vapor transmission. It allows water vapor to escape while blocking liquid water, ensuring dryness and comfort. This type of film is widely used in technical textiles, outdoor apparel, footwear, and medical products that require both high breathability and reliable waterproof performance.

Comparison: TPU High Breathable Waterproof Film vs PU Coating vs PTFE Membrane
| Property | TPU Film (High Breathable) | PU Coating | PTFE Membrane |
|---|---|---|---|
| Breathability (MVTR) | High (up to 10,000+ g/m²/24h) | Medium to High | Very High (20,000+ g/m²/24h) |
| Waterproofness (Hydrostatic Pressure) | Excellent (>10,000 mm H₂O) | Good | Excellent |
| Elasticity & Flexibility | Excellent | Moderate | Low (stiff) |
| Softness & Hand Feel | Soft, skin-friendly | Moderate | Rough, stiff |
| Durability (Wash & Wear Resistance) | High | Medium | High (but prone to pinholes) |
| Processability (Lamination, Bonding) | Easy to laminate and bond | Easy | Difficult, needs special processes |
| Recyclability & Sustainability | Recyclable, eco-friendly | Less eco-friendly (solvent used) | Difficult to recycle |
| Cost Efficiency | Moderate | Low cost | High cost |
Conclusion
TPU breathable film offers an ideal solution balancing comfort, protection, processability, and sustainability, outperforming PU coating in breathability and durability, while offering better flexibility and cost efficiency compared to PTFE membranes.
