Advantages of EVA Interlayer Film Compared to PVB Interlayer Film
By Peter Lin
+What’s Wrong with PVB:
However, PVB Interlayer Film is very sensitive to moisture, which makes it difficult to store and process. It requires high standard of processing condition to care about humidity.
So EVA Interlayer Film is emerging and playing a more and more important roll in laminated glass and decorative art glass world.
+Advantage of Making Laminated Glass with EVA Film Compared with PVB Film
1-EVA Interlayer Film is Less Sensitive of Moisture. And EVA Interlayer Film can be processed in an common rood condition.
2-EVA Interlayer Film is better at mobility when melted and better for laminating with papers, PET, silk, wire net, fabric.
3-EVA Film is good at aging resistance, the aging-resistance can be more than 15years.
4-EVA Film is stronger in adhesive with various materials, PMMA, PET,Metals, Plastic etc.
5-EVA glass laminating line is easier and less cost to install. PVB glass laminating is mainly working in a big autoclave, it’s not suitable for the company to make small quantity creatively designed artistic laminated glass for special requirement of different customers. PVB glass laminating machine is a large investment which would be a barrier for the new company who are interested in laminating glass world.
Can EVA Replace PVB?
Prove 1: In China National Safety Laminated Glass Standard(2009 Edition), the Glass Lamination Ethylene-vinyl acetate EVA Interlayer Film is recognized as a safety interlayer film for safety laminated glass, only if the Glass Lamination Ethylene-vinyl acetate EVA Interlayer Film past the same tests as PVB interlayer film.
Prove 2: And Glass Lamination Ethylene-vinyl acetate EVA Interlayer Film can past the tests which are required for laminated glass with PVB interlayer film, like High Temperature Resistance Test, Radiation Resistance Test, Humidity Resistance Test, Ball Impact Peeling Test, Shot-bag Impact Test etc.
