Catalog:EVA plastic film Product range: Solar cell cellophane series
Synopsis
This cellophane uses in the solar cell seal. Under the normal temperature does not have the coherency, is advantageous for the operation. Then sends the heat generation after the thermo-compression to hand over the association solidification and the cementation enhancement response, has the permanent agglutination seal, is one kind of novel thermosetting hot melt cellophane. Already received the long-term test and the outdoors application with this technical production cellophane seal solar cell. In 2002 obtains the massive uses in the national bright project implementation, the year export ultra 1 million square meters.
The cellophane also is suitable for the lawn lamp, the garden lamp and so on small or the miniature solar cell module lamination seal, has the environmental protection, the long time bears the ultraviolet ray and does not turn yellow and so on the merit.
This company produces can 6 million square meters, the maximum breadth may amount to 2.40 meters.

Suggested initial warm is bigger than 145 ℃, the too low influence hands over the association response and the transparency, then the influence later period is attaching the strength, this cellophane high temperature does not bubble.

Matters needing attention
1. storage conditions: Depositing to cool is dry place, temperature <= 250C, humidity <= 70%;
Avoids the sunlight direct lighting, does not have to approach dust the pollution and so on has the heater and has place
2. Transportation: Should evade the light, evade, damp proof the transportation hotly, smoothly piles up, piles up highly does not have to be many to three,
Does not have to cause the product to be curving and the packing damages.
3. Does not use in directly to contact the cellophane surface, in order to avoid influence cementation performance
4. Does not make an effort to pull the cellophane, in order to avoid has the aberration, affects the performance
5. Does not cause the product to be affected with damp, after opens the packing or the dinking die, should use up as soon as possible.
