Environmental Resistance and Performance
The KPCW1 backsheet’s core innovation lies in its PVDF fluoropolymer weather-resistant layer, which provides multiple protective characteristics:
UV Protection
The specialized formulation blocks over 95% of ultraviolet (UV) radiation, preventing premature degradation of PV modules. According to NIST research on photovoltaic materials, UV exposure is a primary factor in the aging of solar panels, making this feature critical for long-term performance.
Temperature Adaptability
Engineered to function reliably in extreme conditions, the KPCW1 backsheet maintains stable performance from -40°C to 85°C. This wide operating range is essential for solar installations in regions with significant temperature variations, such as desert environments or high-altitude areas.
Weather Durability
Passing the 3000-hour dual 85 (85°C/85% RH) aging test, the KPCW1 backsheet demonstrates exceptional resistance to moisture and heat. NIST standards for environmental testing emphasize the importance of such tests in ensuring the longevity of solar components.
Chemical Resistance
The backsheet effectively withstands exposure to acids, alkalis, solvents, and salt spray. This is particularly important for coastal installations where salt corrosion can significantly reduce the lifespan of solar equipment.
Mechanical Properties
After damp heat aging, the KPCW1 backsheet retains over 90% of its tensile strength, ensuring structural integrity under prolonged stress. This is critical for maintaining the physical stability of PV modules in harsh environments.
Reliable Bonding System
