WHY EVAFORCE® EXTREME-CURVED INTERLAYER FILM BETTER FOR CURVED LAMINATED GLASS?
BY PETER LIN
Why this extreme curve Eva is better fro curve glass, What the special quality does it have?
EVAFORCE® EXTREME-CURVED INTERLAYER FILM owns advanced modified mechanical properties, like adhesive strength, to avoid the potential de-lamination of the stress of curved glass.
This EVA is Super clear, if I compare this product with other this is better regarding to Transparency?
EVAFORCE® EXTREME-CURVED INTERLAYER FILM is better at optical transparency, because it’s the lowest in haze.
For curve glass what the best thickness of the film? why?
Depends on the how curve it is and the flexion square size.
If the curve is light, then 0.38mm EVAFORCE® EXTREME-CURVED INTERLAYER FILM is OK, if the curve is deep, then we suggest 0.76mm EVAFORCE® EXTREME-CURVED INTERLAYER FILM.
The silicon bag for curve glass is the same used in the flat glass, how the correct procedures to laminate a curve glass?
For processing curved glass, the time and temperature of heating and vacuuming is the same. But the vacuuming value should be adjusted to avoid the stress is too high to break the curve glass.
When I supposed to use more than one Eva film between 2 glass?
We have 0.38mm and 0.76 mm thickness EVA FILM, you can choose the thickness that meets the situation.
Yes, you can use two layers EVA FILM to laminate together, but if you need to laminate 0.76mm thickness, one layer of 0.76mm choice is better than 2 layers 0.38 together. Because there will be some air between two layers EVA FILM.
But if you need thicker EVA FILM, then you can use too layers of 0.76mm to get 1.52mm thickness EVA FILM.
How much thickness EVA FILM is needed? It depends on the situation, for example, if you laminate big size tempered(rough surface, uneven) glass, then we suggest you use 0.76mm or thicker.
I always have to use the green tape? when exactly it is required? for example with curve glass I have to use it?
The use of green tape is not essential, you can choose to use or choose not to use.
The function of green tape is to fix the pre-laminated glass, and sometimes it’s used to reduce overflow of EVA FILM when the heating temperature is high and time is long.
So, the use of green tape is decided by the laminating worker.
