Environmental Resistance: Engineered for Extreme Conditions
The KPCW1 solar backsheet is engineered with a PVDF fluoropolymer weather-resistant layer, which provides exceptional protection against environmental degradation. This advanced material ensures that the backsheet maintains its integrity and functionality under challenging conditions. Key features include:
- UV Protection: The formulation blocks over 95% of ultraviolet (UV) radiation, preventing premature aging and discoloration of the solar module.
- Temperature Adaptability: The backsheet operates effectively within a temperature range of -40°C to 85°C, making it suitable for both arctic and desert environments.
- Weather Durability: It passes the 3000-hour dual 85 (85°C/85% RH) aging test, a standard benchmark for long-term reliability in humid and high-temperature conditions.
- Chemical Resistance: The material withstands exposure to acids, alkalis, solvents, and salt spray, ensuring durability in coastal and industrial areas.
- Mechanical Properties: After damp heat aging, the backsheet retains over 90% of its tensile strength, maintaining structural integrity under mechanical stress.
Reliable Bonding System: Ensuring Long-Term Performance
The KPCW1 backsheet features a fluorinated coating cured adhesive layer that ensures robust adhesion to photovoltaic modules. This system has been rigorously tested to meet the demands of diverse applications. Key performance metrics include:
- Peel Strength: Exceeds 60N/cm with EVA, ensuring long-term reliability and resistance to delamination.
- Interface Stability: Demonstrated excellent performance in thermal aging tests, maintaining adhesion under cyclic temperature changes.
- Thermal Cycling: No delamination observed after repeated thermal cycling, confirming its suitability for regions with extreme temperature fluctuations.
- UV Resistance: Passes the 200kWh/m² UV accelerated aging test, ensuring durability in high-irradiation environments.
- Humid Environments: Maintains over 85% bond strength in high-humidity conditions, critical for coastal and tropical regions.
