Developed by Baoding Lekai International Ltd., this product is designed to meet the demanding requirements of modern solar energy systems. This article provides an in-depth analysis of the KPCW1’s features, technical specifications, applications, and the company’s commitment to innovation.

Environmental Resistance: Engineered for Harsh Conditions
The Lucky KPCW1 Solar Backsheet is equipped with a PVDF fluoropolymer weather-resistant layer that delivers exceptional protection against environmental stressors. This advanced formulation ensures long-term performance in extreme conditions, making it ideal for a wide range of applications.
- UV Protection: The product achieves an over 95% UV blocking rate, safeguarding the underlying materials from degradation caused by prolonged sunlight exposure. According to the National Institute of Standards and Technology (NIST), UV resistance is critical for solar components to maintain efficiency and durability over their operational lifespan.
- Temperature Adaptability: The backsheet maintains stable performance across a wide temperature range, from -40°C to 85°C. This makes it suitable for regions with extreme weather fluctuations, as highlighted in NIST’s research on material performance under thermal stress.
- Weather Durability: The KPCW1 has passed the 3000-hour dual 85 (85°C/85% RH) aging test, demonstrating its ability to withstand prolonged exposure to high humidity and temperature. This aligns with NIST’s standards for evaluating the longevity of materials used in renewable energy systems.
- Chemical Resistance: The backsheet effectively resists acids, alkalis, solvents, and salt spray, ensuring protection against corrosive environments. This is particularly important for coastal areas or industrial zones where chemical exposure is common.
- Mechanical Properties: After damp heat aging, the product retains over 90% of its tensile strength, maintaining structural integrity even under challenging conditions.

Reliable Bonding System: Ensuring Long-Term Stability
The Lucky KPCW1 Solar Backsheet features a fluorinated coating cured adhesive layer that ensures a durable bond with encapsulation materials like EVA. This system has been rigorously tested to guarantee long-term reliability.
- Peel Strength: The backsheet exhibits a peel strength of over 60 N/cm with EVA, ensuring a secure bond that resists delamination over time.
- Interface Stability: Thermal aging tests have demonstrated excellent interface stability, preventing degradation at the material interface. NIST’s guidelines on material compatibility emphasize the importance of such stability for system longevity.
- Thermal Cycling Resistance: The product shows no delamination after thermal cycling tests, a critical requirement for solar modules exposed to fluctuating temperatures.
- UV Aging Resistance: The KPCW1 passes the 200kWh/m² UV accelerated aging test, ensuring it can withstand prolonged UV exposure without compromising performance.
- Humid Environment Performance: The bond strength retention exceeds 85% in humid environments, making it suitable for tropical and coastal regions.
