The EVA photovoltaic encapsulation film For Industry has excellent bonding performance, which is mainly due to its special formula and manufacturing process. During the lamination process, the EVA film can quickly melt and tightly bond with the various parts of the photovoltaic module. This tight adhesion not only enhances the structural strength of the module, but also ensures the effective isolation between the cell and the external environment, thereby extending the service life of the module.
Shrinkage is an important indicator to measure the dimensional change of the encapsulation film during heating and pressurization. The EVA photovoltaic encapsulation film For Industry is specially designed to have a low shrinkage rate. This means that during the lamination process, the EVA film can maintain a stable size and shape even under the influence of high temperature and high pressure. Low shrinkage helps to avoid deformation, cracks or internal stress caused by shrinkage of the encapsulation film, thereby ensuring stable quality and long-term reliability of the module.
During the lamination process, the EVA photovoltaic encapsulation film For Industry shows good operability and stability. It can quickly melt and flow under suitable lamination temperature and pressure to fill the gap between the cell and the glass or backplane. At the same time, the EVA film can maintain stable chemical and physical properties and is not affected by high temperature and high pressure. This operability and stability ensure the smooth progress of the lamination process and the tight adhesion of the encapsulation film to the various parts of the module.
EVA photovoltaic encapsulation film For Industry has excellent weather resistance and aging performance. It can resist the erosion of harsh environmental conditions such as ultraviolet rays, high temperature, humidity, etc., and maintain long-term stability and reliability. Even in the long-term use process, the EVA film can maintain excellent adhesion and physical stability, thereby ensuring the long-term stable operation of photovoltaic modules.
Although transmittance is not a characteristic directly related to the stability of the lamination process, the high transmittance of EVA photovoltaic encapsulation film For Industry is crucial to the power generation efficiency of the module. High transmittance means that more sunlight can penetrate the encapsulation film and be absorbed and converted into electrical energy by the cell. This not only improves the power generation efficiency of the module, but also reduces the energy waste caused by light loss. Therefore, high transmittance is one of the key factors to ensure the stable performance of photovoltaic modules and improve power generation efficiency.
