The PVDF fluoropolymer layer of the Lucky KPCW1 backsheet is designed to combat the harshest environmental conditions. Its UV protection capability ensures that solar modules remain efficient even under prolonged exposure to sunlight. The material's ability to function across a wide temperature range (-40°C to 85°C) makes it suitable for both arctic and desert climates. Additionally, the backsheet passes the 3000-hour dual 85 aging test, a stringent standard for weather durability. This resilience is further enhanced by its resistance to chemicals such as acids, alkalis, and solvents, which are common in industrial and coastal environments.
The bonding system of the Lucky KPCW1 backsheet is a critical component of its reliability. The fluorinated coating cured adhesive layer ensures a strong bond with EVA, with peel strength exceeding 60N/cm. This high peel strength guarantees long-term stability, even under thermal cycling and humidity. The backsheet also passes the 200kWh/m² UV accelerated aging test, demonstrating its ability to maintain bond strength in harsh conditions. These features are validated through rigorous thermal aging tests, ensuring that the backsheet remains intact and functional over its operational lifespan.
