Vacuum package for the Ethylene-vinyl acetate EVA Interlayer Film for laminated glass

We, the China Ethylene-vinyl acetate EVA Interlayer Film manufacturer start to use the vacuum package for the Ethylene-vinyl acetate EVA Interlayer Film for laminated glass. The vacuum package can protect the Glass Lamination Ethylene-vinyl acetate EVA Interlayer Film from the moisture and oxidation . So the self life of Glass Lamination Ethylene-vinyl acetate EVA Interlayer Film will be prolonged. And also the vacuum packaged can guarantee that the properties of Glass Lamination Ethylene-vinyl acetate EVA Interlayer Film is working best when laminating with glass.

Don’t worry, no cost will be added. We, the China Ethylene-vinyl acetate EVA Interlayer Film manufacturer will take the cost.

Which Characteristic of Ethylene-vinyl acetate EVA Interlayer Film you care most?

Since Ethylene-vinyl acetate EVA Interlayer Film is more and more popular in the European market.

And the Ethylene-vinyl acetate EVA Interlayer Film manufacturers have kept modifing the properties of Ethylene-vinyl acetate EVA Interlayer Film.

Since we have do a survery of “Would You Use EVA FILM to Replace PVB Film for Architectural Safety Lamianted Glass?“, and today we would like to do a survey of “Which Characteristic of Ethylene-vinyl acetate EVA Interlayer Film you care most?”.

The characteristics of Ethylene-vinyl acetate EVA Interlayer Film are:

transmittance

haze

uv radiation blocking rate

tensile strength Continue reading “Which Characteristic of Ethylene-vinyl acetate EVA Interlayer Film you care most?”

Ethylene-vinyl acetate EVA Interlayer Film for laminated glass is recognized by China National Standard

Ethylene-vinyl acetate EVA Interlayer Film for laminated glass is recognized by China National Standard

All the Ethylene-vinyl acetate EVA Interlayer Film Manufacturers in China hope that Ethylene-vinyl acetate EVA Interlayer Film will be recognized by the Government. Now the  Ethylene-vinyl acetate EVA Interlayer Film is recognized by China National Standard as Safety Glazing Materials in Building. Great News. The standard GB9962-1999 is updated to GB15763.3-2009.

And the Ethylene-vinyl acetate EVA Interlayer Film should passed the same test of PVB polyvinyl butyral interlayer film. The test items include: Heat Resistance, Humidity Resistance, Radiation Resistance, Ball Impact Peeling Resistance, Shot-Bag Impact Resistance.

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.

The Parameters of EVA Film for Laminated Glass(1)

The Parameters of EVA Film for Laminated Glass(1)

By peter shin

Last article i wrote about the cautions of processing laminated glass with EVA FILM.

Today I would like to talk about the parameters of EVA FILM for laminated glass you should care about. And I also would explain how to test these parameters.

1. Radiation Resistance——the most important parameter. It does decide how many years the Laminated Glass with EVA Film can be used for outdoor.

How to test:

Make the laminated glass with EVA FILM subjecting to 2000 hours (different form different standard) of radiation. The samples of laminated glass with EVA Film are placed at a distance of 1,100mm from 16 ULTRAVITALUX lamps which was form a 1m*1m field. The temperature is maintained at 45℃ (5℃ tolerance )and the humidity is 50%.

To measure the durability, the luminous transmission has been measured by the wavelength between 380nm and 780nm before 2,000 hours of exposure to the ULTRAVITALUX lamps.

In the end, compare the differences of Light Transmittance and check the presence of any faults(bubbles, opaqueness, degumming etc)

To be continued
