Architectural EVA Interlayer Film can be used to replace polyvinyl butyral (PVB) interlayer

Solutia declaimed that she is going to expand manufacturing polyvinyl butyral (PVB) interlayer for laminated glass by adding a new plant in Suzhou China.This news makes thinks about the situations of EVA(Ethylene-vinyl acetate) Interlayer Film Plastic Resin. When people talking about the safety architectural laminated glass, they naturally mean that the laminated glass with polyvinyl butyral (PVB) interlayer, seldom people would think of EVA(Ethylene-vinyl acetate) Interlayer Film Plastic Resin. Because people still think that the tensile strength, adhesive strength and weather resistance of EVA(Ethylene-vinyl acetate) Interlayer Film Plastic Resin is not good enough for architectural safety laminated glass. So EVA Interlayer Film Plastic Resin still only can be used in decorative laminated glass.

That’s not true.

Some EVA Interlayer Film Plastic Resin manufacturers have modified the properties of EVA Interlayer Film Plastic Resin , and they invented the Architectural EVA Interlayer Film with can be used to replace polyvinyl butyral (PVB) interlayer.

DuPont™ SentryGlas® Expressions™ Frequently Asked Questions

How do I know if my images are print ready?

A basic rule of thumb is 150 ppi (pixels per inch) are required at the final size of the image. As a reference, images from a website have 72 ppi and are roughly 2” x 2”.

What does “backing” mean?

DuPont has three “backing” options to print an image on: Clear – See through where there is no printing

Soft White (80% Light Transmission) – Light-etched look with no printing

Translucent White (65% Transmission) – Heavier etched look with no printing

What are the benefits of laminated safety glass?

There are multiple benefits of using laminated safety glass. By code, it is a safety glass. Architects have used laminated glass for years to improve security, reduce sound, and lower ultraviolet radiation. New uses include solar control, structural benefits, bomb blast protection and unique decorative applications.

How do I get samples?

There are several sources of samples:

1) General samples can be requested from DuPont or a qualified laminator.

2) Custom samples can be produced; please contact DuPont to determine custom pricing for your specific application.

Great! I found this files from Dupont website.

And i would like share here.

The following info is from www2.dupont.com:

What is SentryGlas® Expressions™?

SentryGlas® Expressions™ is the technology enabling you to create custom colors, and personalized designs, patterns, text, logos, or photographs in laminated safety glass.

How does the technology work?

DuPont prints the custom images on an interlayer, which is then laminated in-between two pieces of glass.

Does DuPont manufacture the finished decorative glass?

No, DuPont works with a network of qualified glass manufacturers (laminators) to laminate the finished glass structure.

How does the process work?

1) Architects or designers…

a. Create the custom concept

b. Specify the glass construction, sizes, and numbers of images/panels

c. Submit print ready files to the glass laminator (or possibly to DuPont)

2) DuPont digitally prints the custom images on interlayers.

3) Qualified glass manufacturers laminate the printed interlayers in-between the specified glass sandwich.

How much does laminated glass with SentryGlas® Expressions™ cost?

DuPont does not produce the final glass product; therefore, pricing must come from the glass manufacturer. As with any project, pricing is dependent on size of job, complexity of design and final glass construction.

How can I get a price estimate quickly?

If the client is not already working with a glass laminator, DuPont can facilitate price discussions with a qualified glass manufacturer. Please provide key information such as project name,

number and size of images/panels and specified glass constructions.

How does the product weather?

DuPont SentryGlas® Expressions™ has excellent weathering because of three factors:

1) Glass – keeps moisture, oxygen and pollutants away from the print

2) Interlayer – blocks up to 99% of the ultraviolet radiation

3) Inks – are formulated to be long-lasting and fade resistant

Are there any warranties?

Yes, DuPont offers a warranty against fade resistance. Qualified glass manufacturers offer a warranty on the final laminated glass construction.

What are the minimum and maximum sizes available?

Typically, no size is too small. The interlayer can be printed up to 94” width by 168” length. Greater lengths may be considered with approval by DuPont and the glass laminator.

Last post i said i sent an email to Mr. Anthony Anderson to ask whether they print the inks directly on the interlayer film.

Now i get the answer from the MaxiGrafix company. And the answer is yes, they do print the inks directly onto the interlayer film.

That’s magical, as i know no China EVA Interlayer film could have done this till now.

The following info is from MaxiGrafix, to learn more, you can go to it’s web site.http://www.maxigrafix.com/index.php/about-us

Decorative Safety Glass has never been more versatile or easy with DigiGlass

SentryGlas® Expressions™ is created by encapsulating a computer or photographic image in full colour, high resolution, in Class One safety glass.

Specially developed proprietary inks and interlayers are used in combination to offer the ideal adhesion, resolution, and dimensional properties needed for artistic imaging in laminated glass.

Decorative Glass the Easy Way

As SentryGlas® Expressions™ uses a computer-based digital imaging system, it is exceptionally efficient and versatile, opening up a broad range of application possibilities.

We can generate art proofs in a day or two (not weeks as is typical with other imaging processes). And when alterations are needed, we can change image content almost as quickly as you make the request. Want four different color versions of the same basic image for comparison? No problem. Want to make a last minute text change? No problem. Want to drop in a new background? No problem.

SentryGlas® Expressions™ doesn’t require tooling, so everything moves faster.

SentryGlas® Expressions™ also gives you more color options. For example, it’s excellent when you need to reproduce multiple skin tones of people in a group photo, or create subtle tonal differences within a scene for dramatic effect.

Just because SentryGlas® Expressions™ is visually dramatic and beautiful, doesn’t mean it isn’t just as strong and practical. The product meets AS2208 Grade A Safety Glass standards making it the ideal solution for any application.

When it’s time to give the glass a quick wipe over, the image inside the glass won’t get damaged. It’s been encapsulated inside the safety glass, remember! That way, solvents and cleaning agents can’t deteriorate the image. Graffiti can’t even deface the image because it can be easily removed from the glass surface.

Wide range of Choices

SentryGlas® Expressions™ lets you create a wide range of transparency levels within a single laminate pane. It’s as versatile as your digital image, so you can have solid colors or high density art or photography in one part of the image and complete clarity elsewhere.

Whether you’re working with thick lines or thin, vibrant colors or subtle tones, dramatic artwork or photography, you can be confident of an accurate reproduction.

If you think your image looks good on your computer screen, just wait till you see it full scale in laminated safety glass.

Case Study: Bubbles of Laminated Glass with EVA Film Interlayer

Case Study: Bubbles of Laminated Glass with EVA Film Interlayer

By Peter Shin

We have seen a situation in this way: Bubbles comes out in the Laminated Glass. And we checks all the details of vacuuming and vacuuming is definitely no problem.

But the bubbles still comes out in the laminated glass. And the bubbles are regular and on lines.

Finally we realized that the bubble lines are right upon the heating pipes.

EVA Film Interlayer manufacturers for Laminated  Glass

So we reduced the temperatures and did the test. Then no bubbles comes out, but some part of laminated glass is not very transparent.

So we know the reason:

Because the heating pipes are under silicon bag, when laminating glass, the part of laminated glass right upon the heating pipes are in higher temperature. And the temperature inside the oven is not in average.

Remember that when the temperature is too high, the copolymer will be breaking up and produce gas which would cause bubbles inside laminated glass.

So we suggest you using the wind-cycle-heating laminating machine to make sure the temperature inside oven is in average.

1.EVA Interlayer Film is less expensive than PVB Interlayer Film.

2.The cost of makeing laminated glass with EVA Interlayer Film is lower than PVB Interlayer Film.

3.PVB glass laminating machine is a large investment which would be a barrier for the new company who are interested in laminating glass world.

4.EVA Interlayer Film is better at mobility when melted and better for laminating with papers, PET, silk, wire net, fabric.

5.As PVB glass laminating machine is mainly working in a big autoclave, it’s not suitable for the company make small quantity creatively designed artistic laminated glass for special requirement of different customers.

6.EVA Interlayer Film is good at water-proof which is a weakness of PVB Interlayer Film.

Can you list more of advantages of EVA Interlayer Film that i miss here, welcome to make up in the comments .

Advantages of EVA Interlayer Film Comparing to PVB Interlayer Film(1)

By Peter Shin

EVA Interlayer Film and PVB Interlayer Film are both used to make laminated glass.

PVB Interlayer Films have been used to make laminated glass for about 40 years.

And EVA Interlayer Films have been used to make laminated glass for about 15 years.

Laminated glass is popular used as safety glass to protect people and property.

Polyvinyl butyral (or PVB) is a resin usually used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughnessand flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobilewindshields. (learn more go to wiki: http://en.wikipedia.org/wiki/Polyvinyl_butyral ) .

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 part in laminated glass and decorative art glass world.

Ethylene vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene.

It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like otherthermoplastics. The material has good clarity and gloss, barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive water proof properties, and resistance to UV radiation. EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications. (learn more go to wiki:http://en.wikipedia.org/wiki/Ethylene-Vinyl_Acetate )
