Product catalog summary
Introduction
The document discusses the development of EPE film, a new material for solar panel encapsulation, driven by the growing demand in the photovoltaic (PV) industry. EPE film combines EVA and POE polymers, offering high adhesion, excellent barrier properties, strong weather resistance, and cost-effectiveness.

The New TSHPTA 082-2024 Standard
A new standard, TSHPTA 082-2024, has been implemented for EPE film used in photovoltaic module encapsulation. Developed by experts from various fields, this standard provides guidelines for performance indicators such as appearance, dimensions, peel strength, shrinkage rate, cross-linking degree, light transmittance, tensile properties, water vapor transmission rate (WVTR), electrical tracking resistance index, and aging performance. Labthink played a significant role in developing this standard.

EPE Film Key Performance Assessment
  • Water Vapor Transmission Rate (WVTR): The standard introduces WVTR as a crucial performance indicator to prevent moisture ingress, which can cause solar module failure. Testing is recommended under specific conditions using methods equivalent to ISO standards.
  • Mechanical Properties: The standard sets higher requirements for tensile performance and peel strength. EPE film must have a tensile strength of ≥10 MPa and elongation at break of ≥600%. Peel strength requirements are also increased, with specific tests for adhesion to glass and backsheet.
  • Enhanced Aging Resistance: The standard includes tests for aging resistance, assessing changes in yellowness index and peel strength after exposure to high voltage, temperature, humidity, and UV radiation. EPE film must maintain a yellowness index of <5.0 and peel strength of >40 N/cm after aging tests.

Conclusion
The TSHPTA 082-2024 standard establishes stringent performance indicators for EPE film, ensuring higher quality and reliability for solar module applications. Labthink continues to support advancements in the solar film industry through its expertise in testing.

EPE Film for Solar Panels-A New Standard for Performance-1

EPE Film for Solar Panels: A New Standard for Performance The rapid growth of the solar (photovoltaic, PV) industry is driving demand for advanced packaging materials for solar modules. This has led to the development of new materials, notably EPE film. Photovoltaic EPE film The New TSHPTA 082-2024 Standard EPE film is a transparent, co-extruded multi-layer film specifically designed for solar panel encapsulation. It combines the benefits of two common polymers EVA and POE. This structure offers a balance of high adhesion, excellent barrier properties, strong weather resistance, and cost-effectiveness. To support the widespread use of EPE film, a new product standard, TSHPTA 082-2024: "Co-extruded EPE film for photovoltaic module encapsulation," has been officially implemented. This standard was developed by a team of experts from various fields, including new energy, new materials, testing instrument development, and research institutions. Labthink, a company specializing in testing instruments, was a key contributor, sharing its expertise in material barrier and mechanical performance testing. They conducted extensive research into EPE film's manufacturing process, application needs, and testing challenges. The new standard sets clear guidelines for many performance indicators of EPE film, including appearance, dimensions, peel strength, shrinkage rate, cross-linking degree, light transmittance, tensile properties, water vapor transmission rate (WVTR), electrical tracking

resistance index and aging performance. This comprehensive standardization is crucial for improving EPE film quality and promoting the healthy development of the industry. EPE Film Key Performance Assessment The TSHPTA 082-2024 standard for EPE film introduces several new performance assessments to the industry. 1. Water Vapor Transmission Rate (WVTR): A Crucial New Requirement Moisture ingress is a major cause of solar module failure, leading to circuit corrosion and delamination. Encapsulant films must block external water vapor to protect cells and extend module life. The new EPE standard...

Peel strength (adhesion to glass, cells, and backsheet) is vital for module stability. The EPE standard not only increases the overall peel strength requirements but also adds new specific tests for peel strength between the film and the backsheet, reflecting real-world application needs.'' The TSHPTA 082-2024 standard for co-extruded EPE film establishes more scientific and stringent performance indicators tailored to current solar module application needs. This provides a consistent reference for EPE film's large-scale production, ensuring higher quality and reliability. Labthink as a contributing...
