0.38mm 0.76mm 1.52mm thermoset EVA Laminated film for Glass
1. Less overflowing : lower Milt index 7-8;
2. Best optical performance and safety performance : 85-95% cross-linking at 120°C laminating.
3. Superior water-proof: open edge application
4. Best anti-aging and durability in outdoor application.
5. Crystalline particle control make EVA film more transparency and cleanliness.
1. The best mechanical performance:
Cross-linking | Extracted in Xylene Solution | >95%(after 150℃ 25mins laminating) | |
Tensile strength | >18MPA | ||
Adhesion with glass | >95N/cm | ||
Water absorption | <0.1% | ||
2.Superior optical performance:
Light transmittance | >90.5% |
Haze | <0.2% |
UV filtering | >99%(390nm wavelength) |
Lighting transmittance decrease | <0.5%(2000hrs UV radiation) |
Yellow index(YI) | <3(2000hrs UV radiation) |
3.Best durability an stability in outdoor climate application:Heat and humidity resistance,Radiation resistance,ball impact peeling test and shot bag impact have been tested for laminated glass with norminal thickness according to GB15763.3-2009 safety glazing materials in building-Part3:Laminated glass
Boilding test(2hrs into 100℃ water) | 5mm glass+0.80mm EVA+5mm glass | Good |
Heat and Humidity resistance test | 85℃ 85%RH,1000hrs | Good |
Anti-aging test | 50℃ 65%RH,UV radiation 2000hrs | Good |
Heat and cold shock test | -40℃ 30mins/80℃ 30mins,50 circles | Good |
impact resistance against shot-bag | GB-15763.3-2009 | Qualified |
Ball impact peeling resistance | GB-15763.3-2009 | Qualified |
1. Prepare and cut the EVA film into right size according to the following structure:
glass+EVA film + glass
2. Put the overlapped glass into silicon bag and seal silicon bag well.
3. Activate vacuum pump for 5-8min till vacuum value reach -0.095Mpa to double checking the vacuum is good.
4 Set up the laminating temp. and time and start heating.The following data based on 5mm glass +0.38mm EVA +5mm glass.
Heating speed | Temp. and holding time | Vaccum Value | |||
First section | 2℃/min | 60℃ | 25mins | -0.095MPA | |
Second section | 2℃/min | 80℃ | 30mins | -0.095MPA | |
Third section | 2℃/min | 120℃ | 45mins | -0.04MPA | |
Remark: The above curves only for reference, the user should do some adjusts according to the process surroudings(temperature and humidity), glass area, glass thicknes,glass type and the machine itself.
Foshan E&N company as a high-tech and professional EVA film manufacturer was founded in2005. we are the only one company in China who just focus on EVA film business. " Professional, High quality, High-Tech" is our spirits.
E&N company have the best workshop in China who equipped three automatic EVA film production machines and all of the workshops are all 10000 class purified dust-free clean room. Thickness computer control and constant temp. and humitiy control make sure each roll EVA film is good and stable quality.
E&N Company follow up our products quality from procurement raw material to final product inspection. we have our own laboratory and full set of test machines to test every batch of production before delivery.
