Lucky KPCw1 Solar Backsheet - Baoding Lekai International Ltd.

Sep . 22, 2025

The Lucky KPCw1 Solar Backsheet represents a significant advancement in photovoltaic (PV) module technology, offering unparalleled environmental resistance and durability. Developed by Baoding Lekai International Ltd., this product is engineered to meet the rigorous demands of modern solar energy systems. This article explores its technical specifications, performance advantages, and applications, supported by authoritative references and comprehensive product data.

Key Features and Technical Specifications

Environmental Resistance Capabilities

The KPCw1 backsheet incorporates a PVDF fluoropolymer weather-resistant layer, delivering exceptional protection against environmental stressors. Key features include:

  • UV Protection: Over 95% UV blocking rate, preventing degradation from prolonged sunlight exposure.
  • Temperature Adaptability: Maintains stability between -40°C and 85°C, suitable for extreme climates.
  • Weather Durability: Passes 3000-hour dual 85 (85°C/85% RH) aging tests, ensuring long-term reliability.
  • Chemical Resistance: Resists acids, alkalis, solvents, and salt spray, ideal for coastal or industrial environments.
  • Mechanical Properties: Retains over 90% tensile strength after damp heat aging, maintaining structural integrity.

Reliable Bonding System

The fluorinated coating cured adhesive layer is designed for long-term performance:

  • Peel Strength: Exceeds 60N/cm with EVA, ensuring robust adhesion.
  • Interface Stability: Demonstrated through thermal aging tests, minimizing delamination risks.
  • UV Resistance: Survives 200kWh/m² UV accelerated aging tests, maintaining bond integrity.
  • Humidity Resistance: Retains over 85% bond strength in humid conditions.

Strict Quality Control Measures

Every batch of KPCw1 undergoes rigorous quality assurance protocols:

  • Comprehensive raw material inspection
  • Real-time monitoring of production parameters
  • 100% finished product appearance and dimensional inspection
  • Regular sampling for accelerated aging tests
  • Complete traceability records for product quality
