Industrial EVA photovoltaic encapsulation film For Industry is a high-performance material specially used for encapsulation of solar photovoltaic modules. Its main function is to firmly bond solar cells to glass and backplanes, protect modules from external environmental influences, and ensure the power generation efficiency and long-term stable operation of modules.

1. Protect modules from PID risks
EVA encapsulation film has excellent electrical insulation properties and resistance to electrical degradation. PID is one of the important reasons for the performance degradation of photovoltaic modules. The film can effectively prevent charge migration, reduce PID risks, and ensure long-term stable power generation of modules.

2. Excellent weather resistance
The encapsulation film can withstand harsh environmental influences such as high temperature, high humidity and strong ultraviolet rays, and has excellent anti-aging ability. Whether in hot deserts, high-humidity tropical rainforests, or high-altitude areas with strong ultraviolet rays, it can maintain its stable performance.

3. Excellent adhesion after aging
With advanced material formula and added antioxidants, EVA film can still maintain good adhesion after long-term outdoor aging, ensuring the stability of the internal structure of the module and avoiding delamination or peeling.

4. Excellent light transmittance
EVA film has high light transmittance, usually up to 90% or more, which maximizes the light transmission, improves the photoelectric conversion efficiency of photovoltaic modules, and enhances power generation performance.

5. Low shrinkage to ensure stable lamination quality
The encapsulation film shows extremely low shrinkage during the lamination process, reduces the internal strain caused by thermal stress, ensures the integrity of the module structure after lamination, and avoids deformation or damage caused by material shrinkage.

6. Good operability and stability
Industrial EVA encapsulation film is suitable for a variety of lamination equipment and processes, with easy operation and stable process, which helps to improve production efficiency and product qualification rate.

7. Wide range of applications
The encapsulation film is widely used in the manufacture of various photovoltaic modules, including single crystal, polycrystalline and thin-film solar cells, to meet the needs of modules of different sizes and types.

High-quality material formula
The EVA encapsulation film is carefully proportioned with polymer materials and additives, and has good chemical stability and thermal stability. This formula makes it less likely to degrade or decay in high temperature and high humidity environments, thereby ensuring the firmness of the bonding layer.

Outstanding anti-aging performance
Under long-term outdoor exposure conditions, the encapsulation film will undergo multiple tests such as ultraviolet radiation, high temperature cycles, and wet heat erosion. Industrial EVA film significantly delays material aging by adding antioxidants and UV stabilizers to ensure that the bonding performance does not decrease over time.

Lamination process optimization
The encapsulation film is designed to be compatible with mainstream lamination processes, and can fully penetrate the component surface during the lamination process to achieve a strong bonding effect. Its low shrinkage helps to avoid cracking or peeling of the bonding interface caused by thermal stress.

After rigorous performance testing
The product has passed a number of international standard tests, including wet heat cycle tests, thermal cycle tests, and UV aging tests, all of which show that its bonding performance can remain excellent under various extreme conditions, ensuring long-term stable operation of the components.
