EVA film is based on the use of ethylene vinyl acetate copolymer, and additives. It is commonly used in the construction industry to form EVA Laminated glass film.

EVA film has good adhesion to glass, with a tough, transparent, temperature, cold, bonding strength, high elongation at break, good moisture resistance and other beneficial characteristics. It can be used for the replacement of PVB (Polyvinyl butyral) materials used in the automotive and construction industry.

In the production of security laminated glass it can contribute to safety, insulation, sound insulation, anti-ultraviolet and other properties. It can be applied to a variety of glass with a glueing process, including; embossed glass, tempered glass, curved glass, building laminated glass, decorative laminated glass, anti-theft glass, plastic sandwich panels and so on.

The advantages of EVA laminated glass film include; high transparency, good adhesion, impact resistance, good durability, resistance to high temperature, moisture, ultraviolet, radiation and so on. It has good durability and low degradation over time, meaning it can be used for long periods outdoors.

Compared to PVB it has a better sound insulation, in particular at high-frequency. It has a low melting point, and is easy to flow.

EVA film can be laminated with PDLC film for smart switchable glass wich can turn from opaque to transparent by connecting the power supply

The HC-TD (80 degree processing EVA film) is a new kind of EVA film developed for PDLC(LCD) smart film, and polycarbonate panel lamination. this must be laminated at 80 degrees, and has high transparency and good adhesion strength to different materials.
