Key Features and Environmental Resistance
The KPCW1 backsheet is designed to withstand extreme environmental conditions, making it ideal for use in challenging locations. Its **PVDF fluoropolymer weather-resistant layer** provides a multi-layered defense against degradation. Here are the key protective features:
- UV Protection: The formulation blocks over 95% of UV radiation, preventing premature aging and discoloration of the PV module.
- Temperature Adaptability: It maintains stability across a wide range of temperatures, from -40°C to 85°C, ensuring performance in both freezing and scorching climates.
- Weather Durability: The backsheet passes a 3000-hour dual 85°C/85% RH aging test, demonstrating resilience against prolonged exposure to moisture and heat.
- Chemical Resistance: It effectively resists acids, alkalis, solvents, and salt spray, making it suitable for coastal and industrial environments.
- Mechanical Properties: After damp heat aging, the material retains over 90% of its tensile strength, ensuring structural integrity.

Reliable Bonding System
The **fluorinated coating cured adhesive layer** of the KPCW1 backsheet is a critical component that ensures long-term reliability. Rigorous testing has validated its performance in various conditions:
- Peel Strength: The bond with EVA (ethylene-vinyl acetate) exceeds 60 N/cm, providing robust adhesion that resists delamination over time.
- Thermal Aging Stability: The interface remains stable even after prolonged exposure to high temperatures, as demonstrated in thermal aging tests.
- Thermal Cycling Resistance: The backsheet shows no signs of delamination after repeated thermal cycling, a common challenge in PV modules.
- UV Aging Resistance: It passes a 200 kWh/m² UV accelerated aging test, ensuring durability under intense sunlight.
- Humid Environment Performance: Over 85% of bond strength is retained in high-humidity conditions, preventing moisture ingress.

Strict Quality Control Measures
Baoding Lekai International Ltd. employs a comprehensive quality control process to ensure the KPCW1 backsheet meets the highest standards. Every batch undergoes:
- Raw Material Inspection: High-quality materials are selected and tested for consistency and purity.
- Real-Time Monitoring: Key production parameters are continuously tracked to maintain precision.
- Appearance and Dimensional Inspection: 100% of finished products are visually and dimensionally checked for defects.
- Accelerated Aging Tests: Regular sampling ensures the product’s longevity under simulated harsh conditions.
- Traceability Records: Detailed records are maintained for full product traceability, ensuring accountability and transparency.
Wide Range of Applications
The KPCW1 backsheet is designed for versatility, making it suitable for a variety of solar projects:
- Utility-Scale Solar Power Plants: Provides reliable protection for large-scale installations.
- Commercial and Industrial Distributed Projects: Ideal for rooftop and ground-mounted systems in urban and industrial areas.
- Coastal Areas with High Humidity: Resists corrosion and moisture damage in seaside environments.
- High-Irradiation Desert Regions: Maintains performance under intense sunlight and extreme temperatures.
- Regions with Large Temperature Variations: Ensures stability in climates with significant day-night temperature swings.
According to the National Institute of Standards and Technology (NIST), “Materials used in solar applications must meet rigorous standards for durability and performance to ensure long-term efficiency and safety.” The KPCW1 backsheet aligns with these standards, offering a solution that meets the demands of modern photovoltaic systems.
