Product Family: EVA Interlayer Films

Decorative optical interlayer film for switchable glass

Ethylene vinyl acetate EVA is a copolymer-based optical interlayer film used to laminate switchable glass composites. These composites or dimmable glass provide switchable on-off privacy for architectural and other decorative glass lamination applications. The film is used as a design feature in highly visible, glass composites located in conference rooms, offices, bedrooms, bathrooms and any other glass-walled or glass-windowed location where visual isolation is desired. 

EVA interlayers are ideal for laminating decorative glass due to its ability to encapsulate objects sandwiched within the glass laminate.  Argotec's high-flow EVAs flow around irregular shaped objects, whereas other interlayers leave voids and bubbles. It also has excellent adhesion to multiple surfaces like aluminum, PET, and more.

Benefits

  • Design - ability to encapsulate objects sandwiched with glass laminate
  • Ease of fabrication - capability to flow around irregular shaped objects without voids or bubbles, excellent adhesion capability
