EVA Solar Cell Encapsulation Film Extrusion Line

By adopting the casting technology, our EVA solar cell encapsulation film extrusion line is developed for producing the EVA solar cell encapsulation film. The main raw material is the EVA (ethylene-vinyl acetate) resin that contains 30%-33% VA (vinyl acetate). It also enables the production of EVA hot melt adhesive film for laminated glasses once changing the formula and the production technique.

Features of Our Production Line
1. The professionally designed stress relieving device can promptly and effectively eliminate the residual stress caused by film stretching or caused during the production. Therefore, the heat shrinkage problem of EVA adhesive films is well solved.

2. The EVA solar cell encapsulation film extrusion line is equipped with unique low-temperature extrusion system which can guarantee good material mixing and plasticizing effects. In the meantime, this system also avoids the advance curing and cross-linking of additives.

3. The specially-designed forming unit perfectly solves the problems as sticking roller and film stripping.

4. It can be manufactured according to the specific requirements of customers.

Characteristics of EVA Adhesive Film
This film comes with the thickness of 0.30-0.80mm and the strengths as environmental protection, long-lasting resistance to UV, non-yellowing, high transparency, strong cohesiveness, ageing resistance, low hot-shrinkage rate, etc.

Main Applications of Films Produced by Our Production Line
1. EVA solar cell adhesive film
This film produced by our EVA solar cell encapsulation film extrusion line is used for solar cell encapsulation. Under normal temperature, it is not adhesive and the operation is very simple. Once hot pressed, it will behave with thermal-crosslinking, curing and adhesion enhancement reactions, thus the permanent adhesive sealing is achieved.

2. EVA adhesive film for laminated glasses
It is a kind of thermosetting adhesive film applicable to the laminated glass. The laminated glass made with this film completely conforms to the national standard GB9962-99 (Safety Glazing Materials in Building).
