High Selective Solar Absorber Film
Key Advantages:
1. Ultra-High Efficiency: Achieves industry-leading >95% solar absorptance (α) and <5% thermal emittance (ε) at 80°C, maximizing heat gain even in low-irradiance conditions.
2. Superior Durability: Exceptional resistance to humidity, UV degradation, and thermal cycling. Maintains peak performance for 20+ years.
3. Modern Production Ready: Precision-coated on flexible substrates (Cu, Al, SS) for seamless integration into automated collector manufacturing. Consistent quality, roll-to-roll processing.
4. Aesthetic Appeal: Premium blue color enhances the visual integration of solar collectors into modern architectural designs.
5. Corrosion Resistant: Robust PVD ceramic-metallic coating protects against oxidation and environmental stressors.
6. Low Cost of Ownership: High efficiency + long lifespan delivers superior ROI compared to conventional black chrome or painted absorbers.
Product Overview:
Advanced Blue High Selective Solar Absorber Film: Maximize Efficiency. Embrace Durability. The Next Generation of Solar Thermal Collection.
High Selective Solar Absorber Film is a state-of-the-art PVD (Physical Vapor Deposition) coated solar absorber film engineered for modern flat plate solar collectors. Featuring a distinctive, aesthetically pleasing deep blue finish, this film delivers exceptional solar energy absorption while minimizing thermal re-radiation losses. Designed for automated, high-volume production lines, High Selective Solar Absorber Film sets the benchmark for performance, longevity, and cost-effectiveness in solar thermal applications.
