Why Switchable Film Break When Laminating with Glass and EVA Interlayer Film？
Wrong Concept:
Some customers made the Smart Glass with EVA Interlayer Film, and the Switchable Transparent Film break away it self, so he
ask EVA Interlayer Film Manufacturers whether the EVA Interlayer Film produce some chemical substance that cause the
Switchable Transparent Film breaking away itself?
Composition Of Switchable Film:
The answer is no. So then what is the real why? Because the Switchable Transparent Film itself is a laminated Film.
Composition of Switchable Transparent Film:
The polymer and the liquid crystals are encapsulated in the Switchable Transparent Film. Both faces of the film are covered
with a transparent, ITO coating. Both ITO coatings are connected to a flat electrical busbar, which is fixed on one of the edges
of the film.
Reason Why Switchable Film Delamination
When the Switchable Transparent Laminated Glass(Glass+EVA Film+Switchable Film+EVA Film+Glass) is being heated and
then cooled, the EVA Interlayer Film, glass and Switchable Transparent Film will follow the Expand from Heat and Contract
from Cold rule.
But Switchable Transparent Film’s is WEAKER in the Expand from Heat and Contract from Cold than the EVA Interlayer Film.
And also the adhesive strength between the EVA Interlayer Film and Switchable Transparent Film is harder than the adhesive
strength between the layers inside the Switchable Transparent Film itself. And the adhesive strength between the EVA Interlayer
Film and glasses is harder than the adhesive strength between the layers inside the Switchable Transparent Film itself. That’s
the reason why the Switchable Transparent Film Break away When Laminating with Glass and EVA Interlayer Film，It's the
EVA Film Shrinkage that break away the Switchable Film.
How to Solve:
Solve:
1.Find a better supplier of EVA Film, whose EVA Film is less in Shrinkage rate.
2. Some EVA Interlayer Film Manufacturers have made the low-temperature (about 80-85 degree) processing EVA Interlayer
Film dedicated for makeing Switchable Transparent Laminated Glass.
With using the low-temperature-processing EVA Interlayer Film, you can solve this problem.
