eva adhesive film
1)solar cell EVA encapsulating filmfor encapaulating solar modules.
2)Excelent UV
3)damp heat resistance
4)long term perform
Our eva is extremely high transparency, suitable cross link rate, small shrinkage, good humidity & UV light resistance.
EVA film is based on EVA resin which basis to (ethylene and vinyl acetate copolymer resin), by adding a variety of modified additives, through melt extrusion made of the rmosetting hot melt film. Not be sticky in normal temperature, easy to operation. Produced by thermal lamination with the bonding enhanced crosslinking chemical reactions, making silicon wafers, glass, TPT multilayer material consisting of one firm bond as the product of solar panels, in actual outdoor applications up to 25 years life. A large number of applications at home and abroad well-proven solar panels, EVA film is the optimum cost performance, it is difficult to alternative packaging materials for solar cells.
Our EVA film's advantages are as follow:
· High Transmittance
· High Mechanical Strength
· High Adhesion Strength
· High Photo- thermal Stability
· High Cross-linking rate
· User-friendly
