What is EVA film?

EVA stands for Ethylene Vinyl Acetate. It is a copolymer resin. The resin, together with a number of ingredients, is heated and mixed thoroughly and is then extruded through a flat die. EVA film is then formed.

EVA film is available with clear, white and many different colors. It contains no plasticizer. It is always packed in roll form. The outstanding adhesive EVA film is non-sticky and its surface is smooth.
EVA film is always used as an interlayer sandwiched in between two pieces of glass or plastic sheet.

EVA Film Is A Revolutionary New Type Of Interlayer For Glass And Plastic Sheet Lamination And Encapsulation Without Autoclaving

Characteristics of EVA Film

  • EVA stands for ethylene vinyl acetate.
  • It is a thermoplastic copolymer resin.
  • EVA resin, together with a number of ingredients, is heated and mixed thoroughly and is then extruded through a flat die of a special design plastic extruding machine.
  • EVA film is then formed. It is finally wind up in roll for storage and packing.
  • This extraordinary adhesive film is non-sticky and inert to water moisture.
  • Handling and glass assembly could be done under room temperature. No air conditioner and no    dehumidifier are required.What are the advantages of EVA film?
    • High tensile strength, ≧21 Mpa
    • Excellent transparency and great light transmission, ≧92%
    • Good adhesion properties, ≧50N /cm
    • UV protection properties, ≧99% UV block
    • Can withstand high temperature
    • Can act as sound barrier
    • Waterproof
    • High wind and weather resistance, ≧15 years
    • Humidity resistant
    • Long tem reliability

      Why EVA Film become so popular?

    • EVA Film is an alternative to PVB, which is costly.

      A few comparisons between EVA Film and PVB

Highly resistance to humidity

8-9 times Lower resistance

Lower absorbance of water

High water absorbance

EVA and PVB are both thermoplastic materials, but they have different inherent properties because of different chemical structures.

Chemical Structure of PVB and EVA

Owing to their molecular structures and arrangements, they are amorphous polymer materials, and that is why both of them have excellent optical properties and thus is the reason why they are widely used in glass lamination. It is however not only de to their optical properties that made them important to be used in glass lamination but also because of their chemical properties. As mentioned above, EVA has better physical and chemical properties than PVB in many aspects.

How EVA interlayers Films are used in glass lamination in general?

Eva laminated glass manufacturing requires only one simple machine. Unlike PVB, no autoclave, roller press, air bag etc are required. EVA film manufacturing can be handled under normal climatic condition unlike PBV.
The only machine required is just a heating over with vacuum utilities.

This machine can be used to make different type of laminated glasses. For examples, it can be used to make laminated glass for decorative and architectural purposes or to make polymer dispersed liquid crystal (PDLC) panel which Is transparent and once voltage is applied, it allows light to pass through and become opaque again when voltage is cut off.

The laminated glass processed using this machine used the special EVA film interlayer, which is sandwiched between two layers of glass to bind the glass. Unlike PVB, EVA film is easily handled under normal climatic conditions. Thus no air-conditioner and de-humidifier are required.

Steps:

  1. When the well EVA film is already sandwiched between two layers ofglass and is loaded, the vacuum is started for 15 minutes at roomtemperature till it reaches 0.095 Mpa.
  2. Heat to low temperature ( 65 oC-70 oC ) and keep for a while ( 30-40min).
  3. The temperature is then increased until the glass surface reaches110 oC-130 oC and maintain temperature for a while (40-50 min). Note that the maintaining time varies according to glass and EVA films thicknesses. Please refer to the table below*

     4. Allow the laminated glass to be cooled below 50 oC. Throughout the cooling process, the vacuum should remain on. If decorative designs are used, it is then recommended to cool down to 40 oC.
5. The vacuum is then turned off and the laminated glass can be unloaded.

 

Uses and applications of EVA films

General Application

1.The basic configuration of EVA laminated glass is to sandwich the EVA film interlayer in between two pieces of glasses.

There are various color choices, from standard clear to super clear, from light white to sandblast white, from transparent red to transparent black, from translucent orange to translucent blue and from opaque yellow to opaque purple, etc.

2. Decorative and Finishing Applications

Design interlayer with images and graphics could be sandwiched in between two pieces of glass encapsulated by two pieces of EVA films. The design interlayer could be any images, graphics and/or any colors.

Decorative EVA interlayer film is often used in combination with PET backing film, photo paper (PP, PVC), silk, metal wire, paper, glass fiber, fabric and so on. More than 20 kinds of colors can be selected to produce a variety of high-grade Very artistic sense of decorative glass, mainly for entertainment hotels, squares, home sliding doors, bathroom and other decorative and decorating.

3. Security purposes

Safety glass is one of the most important applications of EVA film. Owing to its good physical properties after lamination, safety glass with EVA film need to frame installation and can be used for many purposes such as stairs, balcony and others.

 

4. Functional Application

Laminated glass sandwiched with a piece of PDLC film encapsulated by two pieces of EVA film. his electro-chromic PDLC film is connected to electricity power. When voltage is applied, it becomes transparent. When voltage is turn off, it becomes opaque.

5. Solar Application

The most popular use of EVA film in the photovoltaic technology is to sandwich silicon wafer-based in between two pieces of ultra clear roll glass encapsulated by plastic interlayer film.
