The Parameters of EVA Film for Laminated Glass(2)

The Parameters of EVA Film for Laminated Glass(2)

By Peter Shin

I have wrote an post The Parameters of EVA Film for Laminated Glass(1), now we are going to finish the topic.

The Parameters you should care about when check the quality of EVA FILM:

1. Radiation Resistance

Check with post: The Parameters of EVA Film for Laminated Glass(1)

2. Humidity Resistance

Placing the laminated glass with EVA FILM samples vertically inside the climatic chamber and maintaining them for two weeks at a temperature of 50 degrees and 95% relative humidity.  Water condensation on the surface of the laminated glass samples is allowed.

No bubbles or opaqueness are noted in the spacer in any of the laminated glass samples tested. (Bubbles only appear along the edges, but at less than 15mm from it.)

3. Impact Resistance

For example: 45kg shot-bag drop from 1200mm height. It remains unbroken or broken, but no shear or opening is allowed within the test piece, through which a 75mm diameter sphere can pass freely.

4. Ultraviolet Radiation Blocking Rate

Tested by the Light Spectrum Meter.

5. Tensile Strength

Tested by the Universal testing machine

6. Elongation

Tested by the Universal testing machine

7. Adhesive Strength

Tested by the Universal testing machine

8. High Temperature Resistance

Boiled by hot water

9. Visible Light Transmission Rate

Tested by the Light Spectrum Meter

Hope it’s helpful to you.

Features and Benefits of Laminated Glass with EVA FILM or PVB FILM


Features and Benefits of Laminated Glass with EVA FILM or PVB FILM

I read a great website about the Features and benefits of the Laminated Glass with EVA FILM or PVB FILM. I am going to edit it and post in my blog.

Feature and Benefits of Laminated Glass

1. Safety Shatterproof

If the laminated glass with EVA FILM or PVB FILM is broken in earthquakes, blast or by other impact, the interlayer film (PVB FILM or EVA FILM) prevents the glass from disintegrating and keeps the glass intact, preventing injuries from broken glass.

2. Safety Barrier against Penetration

Laminated glass with EVA FILM or PVB FILM acts as barrier against penetration better than a metal shutter, and keeps the room safe from objects blown by a strong storm, such as a typhoon.

3. Intruder Resistant

Laminated glass with EVA FILM or PVB FILM provides longer resistance to forced entry and makes a loud noise even if the intruder uses edged tools to break in.

The Glass Sealant for Laminated Glass with EVA FILM

Today I received a great email.

One of foreign friend has emailed me to talk with weather the automotives’ windshields can be made of the laminated glass with EVA FILM.

Good question.

First I though no problem, because we, as the EVA film manufacturer have keeping trying our best to modify the property of the EVA FILM.

The Glass Sealant for Laminated Glass with EVA FILM

The Glass Sealant for Laminated Glass with EVA FILM

By peter shin

It’s shiny in China today.

Yesterday, I have wrote The EVA FILM is not Adhesive

Today we are going to talk about the Glass Sealant for the Laminated Glass with EVA Film.

1. There are three kinds of glass sealant. They are: Acid, Alkaline, and Neutral.

For laminated glass with EVA FILM, it’s better to use the Neutral Glass Sealant.

And also only the laminated glasses with the outdoor super-clear EVA FILM can be sealed by the Glass Sealant.

But some EVA FILM Manufacturer has produced the Outdoor EVA Film can be used with Acid Glass Sealant. But, please check with the EVA FILM Manufacturer before you are going to use the Acid Glass Sealant.

Note: The Acid Glass Sealant is better in adhesion than Neutral Glass Sealant.

2. The manufacturers for the glass sealant:

1) Dow Corning is a great brand for the silicon glass sealant. Lean more.

2) There are some manufacturers in China producing the glass sealant. Their products are great too. Learn more.

3. Like the EVA FILM which has many colors, the glass sealant also has many colors to match the glasses.

Hope it’s helpful to you.

The EVA FILM is not Adhesive(2)

The EVA FILM is not Adhesive(2)

By peter shin

Have you faced the problem that the EVA FILM is not adhesive or not very adhesive when laminating glass with EVA FILM?

I have wrote The EVA FILM is not Adhesive(1)

Now we are going to finish the topic.

4. There is some organic solution on the surface of the glasses. For example oily substance will also do harm to the adhesion of EVA FILM.

Please clean the glasses if necessary. You can use clean water, industrial alcohol, Acetone to clean the glasses.

5. When laminated with the painting papers (like PP, PVC), the printing ink is too much and not being dried.

Please dry the printing papers first before laminating with glasses and EVA FILM.

6. If you found the degumming is happening in the edges of the laminated glass, here is why:

1) The worker‘s hand tough the edges of the glasses, and there are oily substance in the hand, which will do harm to the adhesion of the EVA FILM.

Please ask your worker to wear gloves.

2.) Maybe its summer, and your worker work very hard, and their hands are sweaty. And the sweat will do harm to the EVA FILM.

Please wear gloves.
