EVA films are a key material used for traditional solar panel lamination. What are ethylene vinyl acetate (EVA) films? In the solar industry, the most common encapsulation is with cross-linkable ethylene vinyl acetate (EVA). With the help of a lamination machine, the cells are laminated between films of EVA in a vacuum, which is under compression.

epe胶膜，即“eva-poe-eva”三层复合结构膜，是将eva材料和poe材料进行复合改性，通过共挤工艺制造而成，属于共挤型poe胶膜。 用料方面，POE树脂占60%、EVA树脂约占40%。

2021年10月12日 · Ethylene/Vinyl Acetate Copolymer (EVA) is widely used for encapsulating solar modules. Because it offers the following properties which are desired for solar modules: High electrical resistance makes it a good electrical insulator. Excellent optical transmission. EVA is a material that has been used in the PV industry for decades.

Solar EVA sheets play an important part in enhancing the durability and performance of solar panels. They enable the solar cells to ‘float’ between the glass and the backsheet, helping to soften shocks and vibrations and protecting the cells and their circuits.

Improper use of EVA will have fatal flaws in solar panels. EVA is a resin product of ethylene-vinyl acetate copolymer. The product has good softness, impact strength, environmental stress crack resistance and good optical properties, low temperature resistance and non-toxic properties in a wide temperature range.

EVA (ethyl vinyl acetate) is the most commonly used encapsulant material. EVA comes in thin sheets which are inserted between the solar cells and the top surface and the rear surface. This sandwich is then heated to 150 °C to polymerize the EVA and bond the module together.

In the solar industry, ethylene-vinyl acetate (EVA) film is widely used to encase photovoltaic (PV) modules. This essential component shields solar cells from external elements including moisture, UV light, and heat stress. We provide high-performance EVA sheets that are rigorously validated and tested for quality.

In 2011, Brij started the first plant in India for manufacturing Solar EVA encapsulants and has since been a leader in manufacturing high quality encapsulants for the solar industry. Backed by more than 25 yrs of EVA processing experience, the company has complete expertise and understanding of the product as well as the technology.
