eva photovoltaic film

eva photovoltaic film, the full name is ethylene-vinyl acetate copolymer photovoltaic film, is a material used for packaging photovoltaic cell modules. it is mainly composed of eva resin, cross-linking agent, silane coupling agent and other modifiers. after stirring evenly in the mixer, mix the mixture in a closed container and let it stand for a period of time. the mixture is extracted and placed in the film production line, and is cast and extruded into a molten film. after the molten adhesive film is cooled by multiple cooling rollers, it is trimmed and rolled into a roll; it is non-sticky at room temperature and is easy to operate. when components are laminated, the eva is heated to a certain temperature and is in a molten state to achieve bonding.

the advantages of eva photovoltaic film mainly include:

1. high transparency: the transparency of eva material is significantly higher than some other materials, allowing the original color and design of photovoltaic cell modules to be fully displayed.

1. high wear resistance: eva material has high wear resistance, which can effectively extend the service life of photovoltaic films.

1. good elasticity: eva material has good elasticity and can adapt well to the shape changes of photovoltaic cell components and provide a comfortable feel.

1. not easy to deform: compared with other materials, eva material has a smaller degree of deformation and can maintain its flatness for a longer period of time.

when choosing eva photovoltaic film, you also need to pay attention to the following points:

1. choose the corresponding photovoltaic film according to your photovoltaic module model to ensure a perfect fit.

1. check the thickness and elasticity of the photovoltaic film to ensure it can provide adequate protection without affecting the user experience.

1. pay attention to the cleaning and maintenance of the photovoltaic film, and regularly clean the dust and stains on the surface of the photovoltaic film to keep it in good condition.

in general, eva photovoltaic film is a good choice for photovoltaic module protection, which can not only protect the module from dust and wear, but also provide a comfortable feel and beautiful appearance.
