Seekan interlayer
film used for encapsulation of solar cells:
Solar cells are connected and placed between a tedlar
plate on the bottom and a tempered glass on the top. The
tedlar plate that placed between the solar cells and the
glass is called EVA (ethylene-vinyl-acetate) film, which
is used for encapsulation of cells in standard modules.
Seekan interlayer film used for encapsulation of solar
cells not only can increase the insertion of module components,
but also increases the efficiency of PV module. Also,
it provides the superior protection against the damage
caused by the environment, lasts the use of module shelf-life,
and increases module's cost efficiency. |

| Instruction |
| Seekan interlayer film is
used in the encapsulationof solar cells, which had been
through the process of heat current squeeze out moulded
products. The film is cohesionless in normal temperature,it
is convenient for cut operation through the process of
heat pressing, it will be a solidified Heat-sensitive
and splicing reinforced reaction, to produce a permanent
agglutinate encapsulation,it is a new style thermoset
hot melt film. |

| Preservation
And Transportation |
| Avoid sunlight,heat (above 30¡æ in tempreture),
moisture(above 50% in humidity),pressure and stab. |
