What is EVA

EVA, or ethylene-vinyl acetate copolymer, is synthesized through the copolymerization of ethylene (E) and vinyl acetate (VA). This versatile material, commonly known as EVA or E/VAC, exhibits notable advantages over polyethylene. The incorporation of vinyl acetate into its molecular structure results in reduced crystallinity, enhanced flexibility, superior impact resistance, improved compatibility with fillers, and better heat sealing capabilities. The performance characteristics of EVA resin are primarily influenced by the proportion of vinyl acetate present in its molecular chain. This composition can be tailored to suit various application requirements; as the vinyl acetate content increases, the material's transparency, softness, and toughness are correspondingly enhanced.

EVA characteristics

1. Durability

Premium EVA film is known for its outstanding durability, even under harsh weather conditions such as high temperature and high humidity.

2. Bonding

"When optimal conditions are met, EVA film exhibits remarkable adhesion to solar glass, as opposed to standard glass, which features a rough surface. Additionally, EVA forms a strong bond with the backsheet."

3. Optical

"EVA is renowned for its remarkable transparency, which ensures that light transmission is optimal, allowing ample sunlight to reach the solar cells without significant obstruction. Currently, numerous manufacturers in Asia are utilizing transparent backing, facilitating light permeability between the cells. This innovative design is referred to as a translucent module."

The EVA Film Making Machine extrusion production line utilizes EVA resin, with a VA content ranging from 30% to 33%, as its primary raw material to manufacture EVA film specifically designed for solar photovoltaic cells. Additionally, by adjusting the formulation and process, this production line is capable of producing hot-melt adhesive EVA interlayer films.
