Ethylene Vinyl Acetate (EVA) film and Polyvinyl Butyral (PVB) film are two different polymer materials that can be used for glass laminated structures. PVB has been the reference material for the glass lamination on building construction and transportation industries for many years. EVA is challenging current PVB as a laminated material because of some advantageous properties. In fact is a good material also for such type of applications, and is able to fulfill all the key properties that are required to PVB today. Not just that, it is also able to overcome some of the drawbacks of the PVB, outperforming PVB.

Some of the excellent properties of EVA have been already proved in the photovoltaic market. In that market, EVA demonstrated that fact has been already proved by the millions of squared meters of EVA used in photovoltaic. EVA is the “king” material used for the lamination and construction of photovoltaic modules, to produce energy for long periods of time under extreme operation conditions. At this point we should remember that the photovoltaic modules are being produced and sold with 20 year warranty period. Currently NO other materials have demonstrated to be much more efficient than EVA for such type of applications.

EVA as well as PVB are thermoplastic polymers with some inherent elastic and natural adhesive properties. Compared with the other ones, rigid thermoplastic materials, at room temperature these ones look as “chewy gummy” products. In that sense, they are different from the rigid form thermoplastics and that is why they are named as “soft” polymer materials.

Although both are thermoplastic materials, they are different, mainly because their chemical structures are different, as you can notice in these figures:

From their chemical structures, we can appreciate that PVB basically has got an only basic unit that repeats m times in the polymer chains while EVA has got two. EVA is composed of two different repetitive units, depending on the number (n times in one case and m in another) and depending on how they are distributed into the molecular chains they could give to EVA different properties and performance. According to EVA’s molecular composition we can see different types. For this reason, EVA can be used in an extended range applications because is so much functional thermoplastic than PVB.

APPLICATION GUIDELINES

1.) Substrate surfaces should be clean and dry prior to tape application. Isopropyl alcohol (isopropanol) applied with a lint free wipe or swab should be adequate for removing surface contamination such as dust or finger prints. Do not use “denatured alcohol” or glass cleaners which often contain oily components. Allow the surface to dry for several minutes before applying the tape. More aggressive solvents (such as acetone, methyl ethyl ketene (MEK) or toluene) may be required to remove heavier contamination (grease, machine oils, solder flux, etc.) but should be followed by a final isopropanol wipe as described above.

Note: Be sure to read and follow the manufacturers’ precautions and directions when using primers and solvents.

2.) Apply the tape to one substrate at a modest angle with the use of a squeegee, rubber roller or finger pressure to help reduce the potential for air entrapment under the tape during its application. The liner can be removed after positioning the tape onto the first substrate.

3.) Assemble the part by applying compression to the substrates to ensure a good wetting of the substrate surfaces with the tape. Proper application of pressure (amount of pressure, time applied, temperature applied) will depend upon design of the parts. Rigid substrates are more difficult to bond without air entrapment as most rigid parts are not flat. Use of a thicker tape may result in increased wetting of rigid substrates. Flexible substrates can be bonded to rigid or flexible parts with much less concern about air entrapment because one of the flexible substrates can conform to the other substrates.
